| In the Linux kernel, the following vulnerability has been resolved:
vsock/vmci: fix sk_ack_backlog leak on failed handshake
When vmci_transport_recv_connecting_server() returns an error,
vmci_transport_recv_listen() calls vsock_remove_pending() but never
calls sk_acceptq_removed(). This leaves sk_ack_backlog incremented
permanently.
Repeated handshake failures (malformed packets, queue pair alloc
failure, event subscribe failure) cause sk_ack_backlog to climb
toward sk_max_ack_backlog. Once it reaches the limit the listener
permanently refuses all new connections with -ECONNREFUSED, a
silent denial of service requiring a process restart to recover.
The two existing sk_acceptq_removed() calls in af_vsock.c do not
cover this path: line 764 checks vsock_is_pending() which returns
false after vsock_remove_pending(), and line 1889 is only reached
on successful accept().
Fix by balancing sk_acceptq_added() with sk_acceptq_removed() on
the error path. |

Commit d93231a6bc8a ("ceph: prevent a client from exceeding the MDS
maximum xattr size") moved the required_blob_size computation to before
the __build_xattrs() call, introducing a race.
__build_xattrs() releases and reacquires i_ceph_lock during execution.
In that window, handle_cap_grant() may update i_xattrs.blob with a
newer MDS-provided blob and bump i_xattrs.version. When

| In the Linux kernel, the following vulnerability has been resolved:
fou: Don't allow 0 for FOU_ATTR_IPPROTO.
fou_udp_recv() has the same problem mentioned in the previous
patch.
If FOU_ATTR_IPPROTO is set to 0, skb is not freed by
fou_udp_recv() nor "resubmit"-ted in ip_protocol_deliver_rcu().
Let's forbid 0 for FOU_ATTR_IPPROTO. |
| DoS vulnerability in the browser kernel. Impact: Successful exploitation of this vulnerability may affect availability. |
| When an affected product receives a valid CIP message from an unauthorized or unintended source to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP that instructs the CPU to stop logic execution and enter a fault state, a DoS can occur. This situation could cause loss of availability and a disruption of communication with other connected devices.

| In updateState of GraphicsDriverEnableAngleAsSystemDriverController.java, there is a possible persistent dos issue due to an unusual root cause. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. |
| IBM WebSphere Application Server - Liberty 19.0.0.7 through 26.0.0.5 and IBM WebSphere Application Server 9.0, and 8.5 and WebSphere Application Server Liberty are vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to cause the server to consume memory resources. |
| The kex_input_kexinit function in kex.c in OpenSSH 6.x and 7.x through 7.3 allows remote attackers to cause a denial of service (memory consumption) by sending many duplicate KEXINIT requests. NOTE: a third party reports that "OpenSSH upstream does not consider this as a security issue." |
| Use-after-free vulnerability in the Peer Objects component (aka iepeers.dll) in Microsoft Internet Explorer 6, 6 SP1, and 7 allows remote attackers to execute arbitrary code via vectors involving access to an invalid pointer after the deletion of an object, as exploited in the wild in March 2010, aka "Uninitialized Memory Corruption Vulnerability." |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: tcm_loop: Drain commands in target_reset handler
tcm_loop_target_reset() violates the SCSI EH contract: it returns SUCCESS
without draining any in-flight commands. The SCSI EH documentation
(scsi_eh.rst) requires that when a reset handler returns SUCCESS the driver
has made lower layers "forget about timed out scmds" and is ready for new
commands. Every other SCSI LLD (virtio_scsi, mpt3sas, ipr, scsi_debug,
mpi3mr) enforces this by draining or completing outstanding commands before
returning SUCCESS.
Because tcm_loop_target_reset() doesn't drain, the SCSI EH reuses in-flight
scsi_cmnd structures for recovery commands (e.g. TUR) while the target core
still has async completion work queued for the old se_cmd. The memset in
queuecommand zeroes se_lun and lun_ref_active, causing
transport_lun_remove_cmd() to skip its percpu_ref_put(). The leaked LUN
reference prevents transport_clear_lun_ref() from completing, hanging
configfs LUN unlink forever in D-state:
INFO: task rm:264 blocked for more than 122 seconds.

Fix this by making tcm_loop_target_reset() actually drain commands:
1. Issue TMR_LUN_RESET via tcm_loop_issue_tmr() to drain all commands that
the target core knows about (those not yet CMD_T_COMPLETE).
2. Use blk_mq_tagset_busy_iter() to iterate all started requests and
flush_work() on each se_cmd — this drains any deferred completion work
for commands that already had CMD_T_COMPLETE set before the TMR (which
the TMR skips via __target_check_io_state()). This is the same pattern
used by mpi3mr, scsi_debug, and libsas to drain outstanding commands
during reset. |
| The skge driver 1.5 in Linux kernel 2.6.15 on Ubuntu does not properly use the spin_lock and spin_unlock functions, which allows remote attackers to cause a denial of service (machine crash) via a flood of network traffic. |
| The do_coredump function in fs/exec.c in the Linux kernel 2.6.19 sets the flag variable to O_EXCL but does not use it, which allows context-dependent attackers to modify arbitrary files via a rewrite attack during a core dump. |
| The RpcGetPrinterData function in the Print Spooler (spoolsv.exe) service in Microsoft Windows 2000 SP4 and earlier, and possibly Windows XP SP1 and earlier, allows remote attackers to cause a denial of service (memory consumption) via an RPC request that specifies a large 'offered' value (output buffer size), a variant of CVE-2005-3644. |
| The Bonjour functionality in iChat in Apple Mac OS X 10.3.9 allows remote attackers to cause a denial of service (persistent application crash) via unspecified vectors, possibly related to CVE-2007-0614. |
| The 64-bit versions of Microsoft Visual C++ 8.0 standard library (MSVCR80.DLL) time functions, including (1) localtime, (2) localtime_s, (3) gmtime, (4) gmtime_s, (5) ctime, (6) ctime_s, (7) wctime, (8) wctime_s, and (9) fstat, trigger an assertion error instead of a NULL pointer or EINVAL when processing a time argument later than Jan 1, 3000, which might allow context-dependent attackers to cause a denial of service (application exit) via large time values. NOTE: it could be argued that this is a design limitation of the functions, and the vulnerability lies with any application that does not validate arguments to these functions. However, this behavior is inconsistent with documentation, which does not list assertions as a possible result of an error condition. |
| Microsoft Windows XP and Vista overwrites ARP table entries included in gratuitous ARP, which allows remote attackers to cause a denial of service (loss of network access) by sending a gratuitous ARP for the address of the Vista host. |
| The administrative service in Symantec Veritas Volume Replicator (VVR) for Windows 3.1 through 4.3, and VVR for Unix 3.5 through 5.0, in Symantec Storage Foundation products allows remote attackers to cause a denial of service (memory consumption and service crash) via a crafted packet to the service port (8199/tcp) that triggers a request for more memory than available, which causes the service to write to an invalid pointer. |
| The Linux kernel 2.6.13 and other versions before 2.6.20.1 allows remote attackers to cause a denial of service (oops) via a crafted NFSACL 2 ACCESS request that triggers a free of an incorrect pointer. |
| Microsoft Office 2003 allows user-assisted remote attackers to cause a denial of service (application crash) by attempting to insert a corrupted WMF file. |
| The read_multipart function in cgi.rb in Ruby before 1.8.5-p2 does not properly detect boundaries in MIME multipart content, which allows remote attackers to cause a denial of service (infinite loop) via crafted HTTP requests, a different issue than CVE-2006-5467. |
