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. |
| Mozilla Firefox 2.0.0.20 and earlier allows remote attackers to cause a denial of service (application crash) via nested calls to the window.print function, as demonstrated by a window.print(window.print()) in the onclick attribute of an INPUT element. |
| Unspecified vulnerability in the NFSv4 client module in the kernel on Sun Solaris 10 and OpenSolaris before snv_37, when automountd is used, allows user-assisted remote attackers to cause a denial of service (unresponsive NFS filesystems) via unknown vectors. |
| 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. |
| The Unreal engine, as used in Unreal Tournament 3 1.3, Unreal Tournament 2003 and 2004, Dead Man's Hand, Pariah, WarPath, Postal2, and Shadow Ops, allows remote authenticated users to cause a denial of service (server exit) via multiple file downloads from the server, which triggers an assertion failure when the Closing flag in UnChan.cpp is set. |
| Double free vulnerability in the NFS component in Apple Mac OS X 10.4 through 10.4.10 allows remote authenticated users to execute arbitrary code via a crafted AUTH_UNIX RPC packet. |
| 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. |
| Unspecified vulnerability in dbasvr in CA BrightStor ARCServe BackUp v9.01 through R11.5, and Enterprise Backup r10.5, has unknown impact and attack vectors related to memory corruption. |
| Unspecified vulnerability in the CIP dissector in Wireshark (formerly Ethereal) 0.9.14 to 0.99.6 allows remote attackers to cause a denial of service (crash) via unknown vectors that trigger allocation of large amounts of memory. |
| The BDB backend for slapd in OpenLDAP before 2.3.36 allows remote authenticated users to cause a denial of service (crash) via a potentially-successful modify operation with the NOOP control set to critical, possibly due to a double free vulnerability. |
| The OSCAR protocol plugin in libpurple in Pidgin before 2.6.3 and Adium before 1.3.7 allows remote attackers to cause a denial of service (application crash) via crafted contact-list data for (1) ICQ and possibly (2) AIM, as demonstrated by the SIM IM client. |
| The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x before 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory. |
| 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. |
| in.lpd in the print service in Sun Solaris 8 and 9 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors that trigger a "fork()/exec() bomb." |
| Double free vulnerability in the gss_krb5int_make_seal_token_v3 function in lib/gssapi/krb5/k5sealv3.c in MIT Kerberos 5 (krb5) has unknown impact and attack vectors. |
| 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. |
| Use-after-free vulnerability in the frpr_icmp function in the ipfilter (aka IP Filter) subsystem in Sun Solaris 10, and OpenSolaris snv_45 through snv_110, allows remote attackers to cause a denial of service (panic) via unspecified vectors. |
| Mozilla Firefox before 3.0.12 and Thunderbird allow remote attackers to cause a denial of service (memory corruption and application crash) or execute arbitrary code via vectors involving double frame construction, related to (1) nsHTMLContentSink.cpp, (2) nsXMLContentSink.cpp, and (3) nsPresShell.cpp, and the nsSubDocumentFrame::Reflow function. |
| Mozilla Firefox before 3.0.12 does not properly handle an SVG element that has a property with a watch function and an __defineSetter__ function, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted document, related to a certain pointer misinterpretation. |
| The mincore function in the Linux kernel before 2.4.33.6 does not properly lock access to user space, which has unspecified impact and attack vectors, possibly related to a deadlock. |
