CVSS v3.1 |
| 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

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. |
| Unspecified vulnerability in the Bluetooth RFCOMM dissector in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via unknown packets. |
| The FlexGrid ActiveX control in Microsoft Visual Basic 6.0, Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2, Office FrontPage 2002 SP3, and Office Project 2003 SP3 does not properly handle errors during access to incorrectly initialized objects, which allows remote attackers to execute arbitrary code via a crafted HTML document, related to corruption of the "system state," aka "FlexGrid Control Memory Corruption Vulnerability." |
| Adobe Reader and Acrobat 8.1.2 and earlier, and before 7.1.1, allow remote attackers to execute arbitrary code via a crafted PDF document that (1) performs unspecified actions on a Collab object that trigger memory corruption, related to a GetCosObj method; or (2) contains a malformed PDF object that triggers memory corruption during parsing. |
| The SIP module in Ingate Firewall before 4.6.1 and SIParator before 4.6.1 does not reuse SIP media ports in unspecified call hold and send-only stream scenarios, which allows remote attackers to cause a denial of service (port exhaustion) via unspecified vectors. |
| The unmew11 function in libclamav/mew.c in libclamav in ClamAV before 0.92.1 has unknown impact and attack vectors that trigger "heap corruption." |
| Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the JavaScript engine and (1) misinterpretation of the characteristics of Namespace and QName in jsxml.c, (2) misuse of signed integers in the nsEscapeCount function in nsEscape.cpp, and (3) interaction of JavaScript garbage collection with certain use of an NPObject in the nsNPObjWrapper::GetNewOrUsed function in nsJSNPRuntime.cpp. |
| The HTTP_Request_Parser method in the HTTP Transport component in IBM WebSphere Application Server (WAS) 6.0.2 before 6.0.2.31 allows remote attackers to cause a denial of service (controller 0C4 abend and application hang) via a long HTTP Host header, related to "storage overlay" on the stack and a "parse failure." |
| Active Directory in Microsoft Windows 2000 SP4 does not properly allocate memory for (1) LDAP and (2) LDAPS requests, which allows remote attackers to execute arbitrary code via a crafted request, aka "Active Directory Overflow Vulnerability." |
| Symantec Decomposer, as used in certain Symantec antivirus products including Symantec Scan Engine 5.1.2 and other versions before 5.1.6.31, allows remote attackers to cause a denial of service (memory consumption) via a malformed RAR file to the Internet Content Adaptation Protocol (ICAP) port (1344/tcp). |
| libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281. |
| Microsoft Office Excel 2000 SP3 allows remote attackers to execute arbitrary code via a crafted Excel spreadsheet that contains a malformed object, which triggers memory corruption during the loading of records from this spreadsheet, aka "File Format Parsing Vulnerability." |
| Stack-based buffer overflow in Microsoft Internet Explorer 5.01 SP4, 6 SP1 on Windows 2000, and 6 on Windows XP and Server 2003 does not properly handle extraneous data associated with an object embedded in a web page, which allows remote attackers to execute arbitrary code via crafted HTML tags that trigger memory corruption, aka "HTML Rendering Memory Corruption Vulnerability." |
| Unspecified vulnerability in Foundation, as used in Apple iPhone 1.0 through 1.1.2, iPod touch 1.1 through 1.1.2, and Mac OS X 10.5 through 10.5.1, allows remote attackers to cause a denial of service (application termination) or execute arbitrary code via a crafted URL that triggers memory corruption in Safari. |
| Unspecified vulnerability in Apple QuickTime before 7.4 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via a movie file with Image Descriptor (IDSC) atoms containing an invalid atom size, which triggers memory corruption. |
| A "memory calculation error" in Microsoft PowerPoint Viewer 2003 allows remote attackers to execute arbitrary code via a PowerPoint file with an invalid picture index that triggers memory corruption, aka "Memory Calculation Vulnerability." |
| ovtopmd in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allows remote attackers to cause a denial of service (crash) via a crafted TCP request that triggers an out-of-bounds memory access. |
| unzoo.c, as used in multiple products including AMaViS 2.4.1 and earlier, allows remote attackers to cause a denial of service (infinite loop) via a ZOO archive with a direntry structure that points to a previous file. |
| httputils.rb in WEBrick in Ruby 1.8.1 and 1.8.5, as used in Red Hat Enterprise Linux 4 and 5, allows remote attackers to cause a denial of service (CPU consumption) via a crafted HTTP request. NOTE: this issue exists because of an incomplete fix for CVE-2008-3656. |
| The DOC.print function in the Adobe JavaScript API, as used by Adobe Acrobat and Reader before 8.1.2, allows remote attackers to configure silent non-interactive printing, and trigger the printing of an arbitrary number of copies of a document.
