CVSS v3.1 |
| 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.
rm D 0 264 258 0x00004000
Call Trace:

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. |
| kmxIds.sys before 7.3.1.18 in CA Host-Based Intrusion Prevention System (HIPS) 8.1 allows remote attackers to cause a denial of service (system crash) via a malformed packet. |
| The xmlCurrentChar function in libxml2 before 2.6.31 allows context-dependent attackers to cause a denial of service (infinite loop) via XML containing invalid UTF-8 sequences. |
| The data-link switching (DLSw) component in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (device restart or memory consumption) via crafted (1) UDP port 2067 or (2) IP protocol 91 packets. |
| Apple QuickTime before 7.4 allows remote attackers to execute arbitrary code via a movie file containing a Macintosh Resource record with a modified length value in the resource header, which triggers heap corruption. |
| Use-after-free vulnerability in the fasync_helper function in fs/fcntl.c in the Linux kernel before 2.6.33-rc4-git1 allows local users to gain privileges via vectors that include enabling O_ASYNC (aka FASYNC or FIOASYNC) on a locked file, and then closing this file. |
| Multiple memory leaks in the (1) IP and (2) IPv6 multicast implementation in the kernel in Sun Solaris 10, and OpenSolaris snv_67 through snv_93, allow local users to cause a denial of service (memory consumption) via vectors related to the association of (a) DL_ENABMULTI_REQ and (b) DL_DISABMULTI_REQ messages with ARP messages. |
| The regular expression engine (regex.c) in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 allows remote attackers to cause a denial of service (infinite loop and crash) via multiple long requests to a Ruby socket, related to memory allocation failure, and as demonstrated against Webrick. |
| Linux kernel 2.6.17, and other versions before 2.6.22, does not check when a user attempts to set RLIMIT_CPU to 0 until after the change is made, which allows local users to bypass intended resource limits. |
| Apple QuickTime before 7.5.5 allows remote attackers to cause a denial of service (application crash) via a crafted PICT image that triggers an out-of-bounds read. |
| The SIP channel driver in Asterisk Open Source 1.4.x before 1.4.17, Business Edition before C.1.0-beta8, AsteriskNOW before beta7, Appliance Developer Kit before Asterisk 1.4 revision 95946, and Appliance s800i 1.0.x before 1.0.3.4 allows remote attackers to cause a denial of service (daemon crash) via a BYE message with an Also (Also transfer) header, which triggers a NULL pointer dereference. |
| Linux kernel before 2.6.22.17, when using certain drivers that register a fault handler that does not perform range checks, allows local users to access kernel memory via an out-of-range offset. |
| Unspecified vulnerability in NFS in Apple Mac OS X 10.5 through 10.5.1 allows remote attackers to cause a denial of service (system shutdown) or execute arbitrary code via unknown vectors related to mbuf chains that trigger memory corruption. |
| GDI+ in Microsoft Windows XP SP3 allows remote attackers to cause a denial of service (infinite loop) via a PNG file that contains a certain large btChunkLen value. |
| tun in IP Tunnel in Solaris 10 and OpenSolaris snv_01 through snv_76 allows local users to cause a denial of service (panic) and possibly execute arbitrary code via a crafted SIOCGTUNPARAM IOCTL request, which triggers a NULL pointer dereference. |
| Microsoft Office Visio 2002 SP2, 2003 SP3, and 2007 SP1 does not properly validate object data in Visio files, which allows remote attackers to execute arbitrary code via a crafted file, aka "Memory Validation Vulnerability." |
