[/INST] 'cwe': ['CWE-703'], 'message': 'mm/slab.c: fix SLAB freelist randomization duplicate entries
This patch fixes a bug in the freelist randomization code. When a high
random number is used, the freelist will contain duplicate entries. It
will result in different allocations sharing the same chunk.
It will result in odd behaviours and crashes. It should be uncommon but
it depends on the machines. We saw it happening more often on some
machines (every few hours of running tests).
Fixes: c7ce4f60ac19 ("mm: SLAB freelist randomization")

[/INST] 'cwe': ['CWE-415'], 'message': 'Fix double-free in gdImageWebPtr()
The issue is that gdImageWebpCtx() (which is called by gdImageWebpPtr() and
the other WebP output functions to do the real work) does not return whether
it succeeded or failed, so this is not checked in gdImageWebpPtr() and the
function wrongly assumes everything is okay, which is not, in this case,
because there is a size limitation for WebP, namely that the width and
height must by less than 16383.
We can't change the signature of gdImageWebpCtx() for API compatibility
reasons, so we introduce the static helper _gdImageWebpCtx() which returns
success respective failure, so gdImageWebpPtr() and gdImageWebpPtrEx() can
check the return value. We leave it solely to libwebp for now to report
warnings regarding the failing write.

As reported in #86, the binary plist parser would force the type of the

an invalid pointer; e.g. if the node is of type integer, its value would
be considered a pointer, and free() would cause an error.

[/INST] 'cwe': ['CWE-416'], 'message': 'BUG#17512527: LIST HANDLING INCORRECT IN MYSQL_PRUNE_STMT_LIST()
Analysis:
---------
Invalid memory access maybe observed when using prepared statements if:
a) The mysql client connection is lost after statement preparation
is complete and
b) There is at least one statement which is in initialized state but
not prepared yet.
When the client detects a closed connection, it calls end_server()
to shutdown the connection. As part of the clean up, the
mysql_prune_stmt_list() removes the statements which has transitioned
beyond the initialized state and retains only the statements which
are in a initialized state. During this processing, the initialized
statements are moved from 'mysql->stmts' to a temporary 'pruned_list'.
When moving the first 'INIT_DONE' element to the pruned_list,
'element->next' is set to NULL. Hence the rest of the list is never
traversed and the statements which have transitioned beyond the
initialized state are never invalidated.
When the mysql_stmt_close() is called for the statement which is not
invalidated; the statements list is updated in order to remove the
statement. This would end up accessing freed memory(freed by the
mysql_stmt_close() for a previous statement in the list).
Fix:
---
mysql_prune_stmt_list() called list_add() incorrectly to create a
temporary list. The use case of list_add() is to add a single
element to the front of the doubly linked list.
mysql_prune_stmt_list() called list_add() by passing an entire
list as the 'element'.
mysql_prune_stmt_list() now uses list_delete() to remove the
statement which has transitioned beyond the initialized phase.
Thus the statement list would contain only elements where the
the state of the statement is initialized.
Note: Run the test with valgrind-mysqltest and leak-check=full
option to see the invalid memory access.'</s> |

[/INST] 'cwe': ['CWE-362', 'CWE-125'], 'message': 'perf/core: Fix concurrent sys_perf_event_open() vs. 'move_group' race
Di Shen reported a race between two concurrent sys_perf_event_open()
calls where both try and move the same pre-existing software group
into a hardware context.
The problem is exactly that described in commit:
f63a8daa5812 ("perf: Fix event->ctx locking")
... where, while we wait for a ctx->mutex acquisition, the event->ctx
relation can have changed under us.
That very same commit failed to recognise sys_perf_event_context() as an
external access vector to the events and thereby didn't apply the
established locking rules correctly.
So while one sys_perf_event_open() call is stuck waiting on
mutex_lock_double(), the other (which owns said locks) moves the group
about. So by the time the former sys_perf_event_open() acquires the
locks, the context we've acquired is stale (and possibly dead).
Apply the established locking rules as per perf_event_ctx_lock_nested()
to the mutex_lock_double() for the 'move_group' case. This obviously means
we need to validate state after we acquire the locks.

This fixes a nasty bug: dccp_send_reset() is called by both DCCPv4 and DCCPv6, but uses
inet_sk_rebuild_header() in each case. This leads to unpredictable and weird behaviour:
under some conditions, DCCPv6 Resets were sent, in other not.

Second is the current server's view of the screen content. The vnc code
uses this to figure which parts of the guest screen did _really_ change
to reduce the amount of updates sent to the vnc clients. It is also

surface gets replaced by a pixman image. The format changes too,
instead of using the guest screen format we'll use fixed 32bit rgb
framebuffer and convert the pixels on the fly when comparing and

Third surface carries the format expected by the vnc client. That isn't

bugs, we now prefer to be very strict about it.
Ideally here we would use skb_set_owner() but this helper does not exist yet,
only CAN seems to have a private helper for that.

commit 2dcab5984841 ("sctp: avoid BUG_ON on sctp_wait_for_sndbuf")
attempted to avoid a BUG_ON call when the association being used for a
sendmsg() is blocked waiting for more sndbuf and another thread did a
peeloff operation on such asoc, moving it to another socket.
As Ben Hutchings noticed, then in such case it would return without
locking back the socket and would cause two unlocks in a row.
Further analysis also revealed that it could allow a double free if the
application managed to peeloff the asoc that is created during the
sendmsg call, because then sctp_sendmsg() would try to free the asoc
that was created only for that call.
This patch takes another approach. It will deny the peeloff operation
if there is a thread sleeping on the asoc, so this situation doesn't
exist anymore. This avoids the issues described above and also honors
the syscalls that are already being handled (it can be multiple sendmsg
calls).
Joint work with Xin Long.

[/INST] 'cwe': ['CWE-284', 'CWE-862'], 'message': 'CVE-2017-5985: Ensure target netns is caller-owned
Before this commit, lxc-user-nic could potentially have been tricked into
operating on a network namespace over which the caller did not hold privilege.
This commit ensures that the caller is privileged over the network namespace by
temporarily dropping privilege.

[/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> |
