[/INST] 'cwe': ['CWE-79'], 'message': 'Fix Cross-Site Session Transfer vulnerability
mod_auth_mellon did not verify that the site the session was created
for was the same site as the site the user accessed. This allows an
attacker with access to one web site on a server to use the same
session to get access to a different site running on the same server.
This patch fixes this vulnerability by storing the cookie parameters
used when creating the session in the session, and verifying those
parameters when the session is loaded.
Thanks to François Kooman for reporting this vulnerability.
This vulnerability has been assigned CVE-2017-6807.'</s> |

[/INST] 'cwe': ['CWE-416', 'CWE-362'], 'message': 'ucount: Remove the atomicity from ucount->count
Always increment/decrement ucount->count under the ucounts_lock. The
increments are there already and moving the decrements there means the
locking logic of the code is simpler. This simplification in the
locking logic fixes a race between put_ucounts and get_ucounts that
could result in a use-after-free because the count could go zero then
be found by get_ucounts and then be freed by put_ucounts.
A bug presumably this one was found by a combination of syzkaller and
KASAN. JongWhan Kim reported the syzkaller failure and Dmitry Vyukov
spotted the race in the code.

__sock_recv_timestamp can be called for both normal skbs (for
receive timestamps) and for skbs on the error queue (for transmit
timestamps).
Commit 1c885808e456
(tcp: SOF_TIMESTAMPING_OPT_STATS option for SO_TIMESTAMPING)
assumes any skb passed to __sock_recv_timestamp are from
the error queue, containing OPT_STATS in the content of the skb.
This results in accessing invalid memory or generating junk
data.
To fix this, set skb->pkt_type to PACKET_OUTGOING for packets
on the error queue. This is safe because on the receive path
on local sockets skb->pkt_type is never set to PACKET_OUTGOING.
With that, copy OPT_STATS from a packet, only if its pkt_type
is PACKET_OUTGOING.

For historical reasons, fsockopen() accepts the port and hostname
separately: fsockopen('127.0.0.1', 80)
However, with the introdcution of stream transports in PHP 4.3,
it became possible to include the port in the hostname specifier:
fsockopen('127.0.0.1:80')
Or more formally: fsockopen('tcp://127.0.0.1:80')
Confusing results when these two forms are combined, however.
fsockopen('127.0.0.1:80', 443) results in fsockopen() attempting
to connect to '127.0.0.1:80:443' which any reasonable stack would
consider invalid.
Unfortunately, PHP parses the address looking for the first colon
(with special handling for IPv6, don't worry) and calls atoi()
from there. atoi() in turn, simply stops parsing at the first
non-numeric character and returns the value so far.
The end result is that the explicitly supplied port is treated
as ignored garbage, rather than producing an error.
This diff replaces atoi() with strtol() and inspects the
stop character. If additional "garbage" of any kind is found,
it fails and returns an error.'</s> |

[/INST] 'cwe': ['CWE-416', 'CWE-476'], 'message': 'fscrypt: remove broken support for detecting keyring key revocation
Filesystem encryption ostensibly supported revoking a keyring key that
had been used to "unlock" encrypted files, causing those files to become
"locked" again. This was, however, buggy for several reasons, the most
severe of which was that when key revocation happened to be detected for
an inode, its fscrypt_info was immediately freed, even while other
threads could be using it for encryption or decryption concurrently.
This could be exploited to crash the kernel or worse.
This patch fixes the use-after-free by removing the code which detects
the keyring key having been revoked, invalidated, or expired. Instead,
an encrypted inode that is "unlocked" now simply remains unlocked until
it is evicted from memory. Note that this is no worse than the case for
block device-level encryption, e.g. dm-crypt, and it still remains
possible for a privileged user to evict unused pages, inodes, and
dentries by running 'sync; echo 3 > /proc/sys/vm/drop_caches', or by
simply unmounting the filesystem. In fact, one of those actions was
already needed anyway for key revocation to work even somewhat sanely.
This change is not expected to break any applications.
In the future I'd like to implement a real API for fscrypt key
revocation that interacts sanely with ongoing filesystem operations ---
waiting for existing operations to complete and blocking new operations,
and invalidating and sanitizing key material and plaintext from the VFS
caches. But this is a hard problem, and for now this bug must be fixed.
This bug affected almost all versions of ext4, f2fs, and ubifs
encryption, and it was potentially reachable in any kernel configured
with encryption support (CONFIG_EXT4_ENCRYPTION=y,
CONFIG_EXT4_FS_ENCRYPTION=y, CONFIG_F2FS_FS_ENCRYPTION=y, or
CONFIG_UBIFS_FS_ENCRYPTION=y). Note that older kernels did not use the
shared fs/crypto/ code, but due to the potential security implications
of this bug, it may still be worthwhile to backport this fix to them.

Overlayfs, however, can be stacked recursively and also may be stacked
on top of ecryptfs or vice versa.
To limit the kernel stack usage we must limit the depth of the
filesystem stack. Initially the limit is set to 2.

[/INST] 'cwe': ['CWE-358'], 'message': 'udp: properly support MSG_PEEK with truncated buffers
Backport of this upstream commit into stable kernels :
89c22d8c3b27 ("net: Fix skb csum races when peeking")
exposed a bug in udp stack vs MSG_PEEK support, when user provides
a buffer smaller than skb payload.
In this case,
skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr),
msg->msg_iov);
returns -EFAULT.
This bug does not happen in upstream kernels since Al Viro did a great
job to replace this into :
skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg);
This variant is safe vs short buffers.
For the time being, instead reverting Herbert Xu patch and add back
skb->ip_summed invalid changes, simply store the result of
udp_lib_checksum_complete() so that we avoid computing the checksum a
second time, and avoid the problematic
skb_copy_and_csum_datagram_iovec() call.
This patch can be applied on recent kernels as it avoids a double
checksumming, then backported to stable kernels as a bug fix.

On an ext4 or f2fs filesystem with file encryption supported, a user
could set an encryption policy on any empty directory(*) to which they
had readonly access. This is obviously problematic, since such a
directory might be owned by another user and the new encryption policy
would prevent that other user from creating files in their own directory
(for example).
Fix this by requiring inode_owner_or_capable() permission to set an
encryption policy. This means that either the caller must own the file,
or the caller must have the capability CAP_FOWNER.
(*) Or also on any regular file, for f2fs v4.6 and later and ext4
v4.8-rc1 and later; a separate bug fix is coming for that.

[/INST] 'cwe': ['CWE-732'], 'message': '9pfs: local: set the path of the export root to "."
The local backend was recently converted to using "at*()" syscalls in order
to ensure all accesses happen below the shared directory. This requires that
we only pass relative paths, otherwise the dirfd argument to the "at*()"
syscalls is ignored and the path is treated as an absolute path in the host.
This is actually the case for paths in all fids, with the notable exception
of the root fid, whose path is "/". This causes the following backend ops to
act on the "/" directory of the host instead of the virtfs shared directory
when the export root is involved:
- lstat
- chmod
- chown
- utimensat
ie, chmod /9p_mount_point in the guest will be converted to chmod / in the
host for example. This could cause security issues with a privileged QEMU.
All "*at()" syscalls are being passed an open file descriptor. In the case
of the export root, this file descriptor points to the path in the host that
was passed to -fsdev.
The fix is thus as simple as changing the path of the export root fid to be
"." instead of "/".
This is CVE-2017-7471.

If a malicious client pretends to be the E17 window manager, it is
possible to trigger an out of boundary heap write while receiving an
IPC message.
The length of the already received message is stored in an unsigned
short, which overflows after receiving 64 KB of data. It's comparably
small amount of data and therefore achievable for an attacker.
When len overflows, realloc() will either be called with a small value
and therefore chars will be appended out of bounds, or len + 1 will be
exactly 0, in which case realloc() behaves like free(). This could be
abused for a later double-free attack as it's even possible to overwrite
the free information -- but this depends on the malloc implementation.
