/*---------------------------------------------------------------------------
The basic idea of this function is as follows. Since the central di-
rectory lies at the end of the zipfile and the member files lie at the
beginning or middle or wherever, it is not very desirable to simply
read a central directory entry, jump to the member and extract it, and
then jump back to the central directory. In the case of a large zipfile
this would lead to a whole lot of disk-grinding, especially if each mem-
ber file is small. Instead, we read from the central directory the per-
tinent information for a block of files, then go extract/test the whole
block. Thus this routine contains two small(er) loops within a very
large outer loop: the first of the small ones reads a block of files
from the central directory; the second extracts or tests each file; and
the outer one loops over blocks. There's some file-pointer positioning
stuff in between, but that's about it. Btw, it's because of this jump-
ing around that we can afford to be lenient if an error occurs in one of
the member files: we should still be able to go find the other members,
since we know the offset of each from the beginning of the zipfile.

This detects an invalid zip file that has at least one entry that
overlaps with another entry or with the central directory to the
end of the file. A Fifield zip bomb uses overlapped local entries

zip file is rejected.
See https://www.bamsoftware.com/hacks/zipbomb/ for David Fifield's

The detection maintains a list of covered spans of the zip files
so far, where the central directory to the end of the file and any
bytes preceding the first entry at zip file offset zero are
considered covered initially. Then as each entry is decompressed
or tested, it is considered covered. When a new entry is about to
be processed, its initial offset is checked to see if it is
contained by a covered span. If so, the zip file is rejected as
invalid.

NOTES APPLICABLE TO ALL STRING FUNCTIONS:
All of the x_to_y functions take parameters for an output buffer and
its available length, and return an int. The value returned is the
length of the string that the input produces, which may be larger than
the provided buffer length. If the returned value is less than the
buffer length, then the contents of the buffer will be null-terminated;
otherwise, it will not be terminated and may be invalid, possibly
stopping in the middle of a multibyte sequence.
In all cases you may pass NULL as the buffer and/or 0 as the length, if
you just want to learn how much space the string is going to require.
The functions will return -1 if the input is invalid UTF-8 or cannot be
encoded as UTF-8.

/* wide_to_escape_string
provides a string that represents a wide char not in local char set
An initial try at an algorithm. Suggestions welcome.
According to the standard, Unicode character points are restricted to
the number range from 0 to 0x10FFFF, respective 21 bits.
For a hexadecimal notation, 2 octets are sufficient for the mostly
used characters from the "Basic Multilingual Plane", all other
Unicode characters can be represented by 3 octets (= 6 hex digits).
The Unicode standard suggests to write Unicode character points
as 4 resp. 6 hex digits, preprended by "U+".
(e.g.: U+10FFFF for the highest character point, or U+0030 for the ASCII
digit "0")
However, for the purpose of escaping non-ASCII chars in an ASCII character
stream, the "U" is not a very good escape initializer. Therefore, we
use the following convention within our Info-ZIP code:
If not an ASCII char probably need 2 bytes at least. So if
a 2-byte wide encode it as 4 hex digits with a leading #U. If
needs 3 bytes then prefix the string with #L. So
#U1234
is a 2-byte wide character with bytes 0x12 and 0x34 while
#L123456
is a 3-byte wide character with bytes 0x12, 0x34, 0x56.
On Windows, wide that need two wide characters need to be converted
to a single number.

[/INST] 'cwe': ['CWE-400'], 'message': 'Detect and reject a zip bomb using overlapped entries.
This detects an invalid zip file that has at least one entry that
overlaps with another entry or with the central directory to the
end of the file. A Fifield zip bomb uses overlapped local entries
to vastly increase the potential inflation ratio. Such an invalid
zip file is rejected.
See https://www.bamsoftware.com/hacks/zipbomb/ for David Fifield's
analysis, construction, and examples of such zip bombs.
The detection maintains a list of covered spans of the zip files
so far, where the central directory to the end of the file and any
bytes preceding the first entry at zip file offset zero are
considered covered initially. Then as each entry is decompressed
or tested, it is considered covered. When a new entry is about to
be processed, its initial offset is checked to see if it is
contained by a covered span. If so, the zip file is rejected as
invalid.
This commit depends on a preceding commit: "Fix bug in
undefer_input() that misplaced the input state."'</s> |

NOTES APPLICABLE TO ALL STRING FUNCTIONS:
All of the x_to_y functions take parameters for an output buffer and
its available length, and return an int. The value returned is the
length of the string that the input produces, which may be larger than
the provided buffer length. If the returned value is less than the
buffer length, then the contents of the buffer will be null-terminated;
otherwise, it will not be terminated and may be invalid, possibly
stopping in the middle of a multibyte sequence.
In all cases you may pass NULL as the buffer and/or 0 as the length, if
you just want to learn how much space the string is going to require.
The functions will return -1 if the input is invalid UTF-8 or cannot be
encoded as UTF-8.

/* wide_to_escape_string
provides a string that represents a wide char not in local char set
An initial try at an algorithm. Suggestions welcome.
According to the standard, Unicode character points are restricted to
the number range from 0 to 0x10FFFF, respective 21 bits.
For a hexadecimal notation, 2 octets are sufficient for the mostly
used characters from the "Basic Multilingual Plane", all other
Unicode characters can be represented by 3 octets (= 6 hex digits).
The Unicode standard suggests to write Unicode character points
as 4 resp. 6 hex digits, preprended by "U+".
(e.g.: U+10FFFF for the highest character point, or U+0030 for the ASCII
digit "0")
However, for the purpose of escaping non-ASCII chars in an ASCII character
stream, the "U" is not a very good escape initializer. Therefore, we
use the following convention within our Info-ZIP code:
If not an ASCII char probably need 2 bytes at least. So if
a 2-byte wide encode it as 4 hex digits with a leading #U. If
needs 3 bytes then prefix the string with #L. So
#U1234
is a 2-byte wide character with bytes 0x12 and 0x34 while
#L123456
is a 3-byte wide character with bytes 0x12, 0x34, 0x56.
On Windows, wide that need two wide characters need to be converted
to a single number.

When trying to align the minimum encryption key size requirement for

Original Bluetooth version up to 2.0 used a security model where the

that the connection initiator is responsible for providing an encrypted
ACL link before any L2CAP communication can happen.
Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and
before devices are causing a regression. The encryption key size check
needs to be moved out of the HCI connection handling into the L2CAP
channel setup.
To achieve this, the current check inside hci_conn_security() has been
moved into l2cap_check_enc_key_size() helper function and then called
from four decisions point inside L2CAP to cover all combinations of

[/INST] 'cwe': ['CWE-327'], 'message': 'Bluetooth: Fix regression with minimum encryption key size alignment
When trying to align the minimum encryption key size requirement for
Bluetooth connections, it turns out doing this in a central location in
the HCI connection handling code is not possible.
Original Bluetooth version up to 2.0 used a security model where the
L2CAP service would enforce authentication and encryption. Starting
with Bluetooth 2.1 and Secure Simple Pairing that model has changed into
that the connection initiator is responsible for providing an encrypted
ACL link before any L2CAP communication can happen.
Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and
before devices are causing a regression. The encryption key size check
needs to be moved out of the HCI connection handling into the L2CAP
channel setup.
To achieve this, the current check inside hci_conn_security() has been
moved into l2cap_check_enc_key_size() helper function and then called
from four decisions point inside L2CAP to cover all combinations of
Secure Simple Pairing enabled devices and device using legacy pairing
and legacy service security model.

[/INST] 'cwe': ['CWE-264', 'CWE-269'], 'message': 'ptrace: Fix ->ptracer_cred handling for PTRACE_TRACEME
Fix two issues:
When called for PTRACE_TRACEME, ptrace_link() would obtain an RCU
reference to the parent's objective credentials, then give that pointer
to get_cred(). However, the object lifetime rules for things like
struct cred do not permit unconditionally turning an RCU reference into
a stable reference.
PTRACE_TRACEME records the parent's credentials as if the parent was
acting as the subject, but that's not the case. If a malicious
unprivileged child uses PTRACE_TRACEME and the parent is privileged, and
at a later point, the parent process becomes attacker-controlled
(because it drops privileges and calls execve()), the attacker ends up
with control over two processes with a privileged ptrace relationship,
which can be abused to ptrace a suid binary and obtain root privileges.
Fix both of these by always recording the credentials of the process
that is requesting the creation of the ptrace relationship:
current_cred() can't change under us, and current is the proper subject
for access control.
This change is theoretically userspace-visible, but I am not aware of
any code that it will actually break.

[/INST] 'cwe': ['CWE-190', 'CWE-125'], 'message': 'floppy: fix out-of-bounds read in copy_buffer
This fixes a global out-of-bounds read access in the copy_buffer
function of the floppy driver.
The FDDEFPRM ioctl allows one to set the geometry of a disk. The sect
and head fields (unsigned int) of the floppy_drive structure are used to
compute the max_sector (int) in the make_raw_rw_request function. It is
possible to overflow the max_sector. Next, max_sector is passed to the
copy_buffer function and used in one of the memcpy calls.
An unprivileged user could trigger the bug if the device is accessible,
but requires a floppy disk to be inserted.
The patch adds the check for the .sect * .head multiplication for not
overflowing in the set_geometry function.
The bug was found by syzkaller.

[/INST] 'cwe': ['CWE-369'], 'message': 'floppy: fix div-by-zero in setup_format_params
This fixes a divide by zero error in the setup_format_params function of
the floppy driver.
Two consecutive ioctls can trigger the bug: The first one should set the
drive geometry with such .sect and .rate values for the F_SECT_PER_TRACK
to become zero. Next, the floppy format operation should be called.
A floppy disk is not required to be inserted. An unprivileged user
could trigger the bug if the device is accessible.
The patch checks F_SECT_PER_TRACK for a non-zero value in the
set_geometry function. The proper check should involve a reasonable
upper limit for the .sect and .rate fields, but it could change the
UAPI.
The patch also checks F_SECT_PER_TRACK in the setup_format_params, and
cancels the formatting operation in case of zero.
The bug was found by syzkaller.

[/INST] 'cwe': ['CWE-200', 'CWE-284', 'CWE-203'], 'message': 'EAP-pwd: fix side-channel leak where 1 in 2018 handshakes fail
Previously the Hunting and Pecking algorithm of EAP-pwd aborted when
more than 10 iterations are needed. Every iteration has a 50% chance
of finding the password element. This means one in every 2048 handshakes
will fail, in which case an error frame is sent to the client. This
event leaks information that can be abused in an offline password
brute-force attack. More precisely, the adversary learns that all 10
iterations failed for the given random EAP-pwd token. Using the same
techniques as in the Dragonblood attack, this can be used to brute-force
the password.
This patch fixes the above issue by executing enough iterations such that
the password element is always found eventually.
Note that timing and cache leaks remain a risk against the current
implementation of EAP-pwd.'</s> |

We find the memory use-after-free issue in __blk_drain_queue()
on the kernel 4.14. After read the latest kernel 4.18-rc6 we
think it has the same problem.
Memory is allocated for q->fq in the blk_init_allocated_queue().
If the elevator init function called with error return, it will
run into the fail case to free the q->fq.
Then the __blk_drain_queue() uses the same memory after the free
of the q->fq, it will lead to the unpredictable event.
The patch is to set q->fq as NULL in the fail case of
blk_init_allocated_queue().
