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. |
| The Workstation service in Microsoft Windows 2000 SP4 and XP SP2 allows remote attackers to cause a denial of service (memory consumption) via a large maxlen value in an NetrWkstaUserEnum RPC request. |
| Use-after-free vulnerability in the Client/Server Run-time Subsystem (CSRSS) in Microsoft Windows Vista does not properly handle connection resources when starting and stopping processes, which allows local users to gain privileges by opening and closing multiple ApiPort connections, which leaves a "dangling pointer" to a process data structure. |
| FTP Explorer 1.0.1 Build 047, and other versions before 1.0.1.52, allows remote servers to cause a denial of service (CPU consumption) via a long response to a PWD command. |
| Guidance Software EnCase allows user-assisted remote attackers to cause a denial of service via (1) a corrupted Microsoft Exchange database, which triggers an application crash when many options are selected; (2) a corrupted NTFS filesystem, which causes the application to report "memory allocation errors;" or (3) deeply nested directories, which trigger an application crash during an Expand All action. NOTE: the vendor disputes the significance of these vectors because the user can select fewer options, there is no operational impact, or the user can do less expansion |
| Memory leak in the push_align function in src/util.c in Vilistextum before 2.6.9 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors related to the tmp_align variable. NOTE: it is not clear whether this is a vulnerability, due to the functionality of the product. |
| PUBCONV.DLL in Microsoft Office Publisher 2007 does not properly clear memory when transferring data from disk to memory, which allows user-assisted remote attackers to execute arbitrary code via a malformed .pub page via a certain negative value, which bypasses a sanitization procedure that initializes critical pointers to NULL, aka the "Publisher Invalid Memory Reference Vulnerability". |
| The __qdisc_run function in net/sched/sch_generic.c in the Linux kernel before 2.6.25 on SMP machines allows local users to cause a denial of service (soft lockup) by sending a large amount of network traffic, as demonstrated by multiple simultaneous invocations of the Netperf benchmark application in UDP_STREAM mode. |
| libclamav/petite.c in ClamAV before 0.93.1 allows remote attackers to cause a denial of service via a crafted Petite file that triggers an out-of-bounds read. |
| pwlib, as used by Ekiga 2.0.5 and possibly other products, allows remote attackers to cause a denial of service (application crash) via a long argument to the PString::vsprintf function, related to a "memory management flaw". NOTE: this issue was originally reported as being in the SIPURL::GetHostAddress function in Ekiga (formerly GnomeMeeting). |
| The JBIG2 MMR decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (infinite loop and hang) via a crafted PDF file. |
| The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 uses the i_size_high structure member during operations on arbitrary types of files, which allows local users to cause a denial of service (CPU consumption and error-message flood) by attempting to mount a crafted ext4 filesystem. |
| Multiple memory leaks in server/MaraDNS.c in MaraDNS before 1.2.12.06, and 1.3.x before 1.3.05, allow remote attackers to cause a denial of service (memory consumption) via (1) reverse lookups or (2) requests for records in a class other than Internet (IN), a different set of affected versions than CVE-2007-3114 and CVE-2007-3116. |
| Memory leak in the http_request_parse function in request.c in lighttpd before 1.4.20 allows remote attackers to cause a denial of service (memory consumption) via a large number of requests with duplicate request headers. |
| Apple QuickTime before 7.6.2 does not properly initialize memory before use in handling movie files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a movie containing a user data atom of size zero. |
| XM Easy Personal FTP Server 5.2.1 and earlier allows remote authenticated users to cause a denial of service via a long argument to the NLST command, possibly involving the -al flags. |
| The getAnnots Doc method in the JavaScript API in Adobe Reader and Acrobat 9.1, 8.1.4, 7.1.1, and earlier allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via a PDF file that contains an annotation, and has an OpenAction entry with JavaScript code that calls this method with crafted integer arguments. |
| Panda ActiveScan 5.53.00, and other versions before 5.54.01, allows remote attackers to (1) reboot the system using the Reinicializar method in the ActiveScan.1 ActiveX control, or (2) determine arbitrary file existence and size via the ObtenerTamano method in the PAVPZ.SOS.1 ActiveX control. |
| The SNMP dissector in Wireshark (formerly Ethereal) 0.99.6 through 0.99.7 allows remote attackers to cause a denial of service (crash) via a malformed packet. |
| Memory leak in server/MaraDNS.c in MaraDNS 1.2.12.06 and 1.3.05 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors, a different set of affected versions than CVE-2007-3114 and CVE-2007-3115. |
