The apply_dependent_coupling function in libavcodec/aacdec.c in Libav 12.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted aac file.

kernel: Null pointer dereference in fs/f2fs/segment.c via mounting fs with noflush_merge option allows local denial of service

fs/f2fs/segment.c in the Linux kernel before 4.13 allows local users to cause a denial of service (NULL pointer dereference and panic) by using a noflush_merge option that triggers a NULL value for a flush_cmd_control data structure.

The Gentoo app-admin/collectd package before 5.7.2-r1 sets the ownership of PID file directory to the collectd account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script sends a SIGKILL (when the service is stopped).

A time-sensitive equality check on the JWT signature in the JsonWebToken.validate method in main/scala/authentikat/jwt/JsonWebToken.scala in authentikat-jwt (aka com.jason-goodwin/authentikat-jwt) version 0.4.5 and earlier allows the supplier of a JWT token to guess bit after bit of the signature by repeating validation requests.

exempi: Infinite loop in TradQT_Manager::ParseCachedBoxes function in XMPFiles/source/FormatSupport/QuickTime_Support.cpp

An issue was discovered in Exempi before 2.4.4. The TradQT_Manager::ParseCachedBoxes function in XMPFiles/source/FormatSupport/QuickTime_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .qt file.

exempi: null pointer dereference in PostScript_Support::ConvertToDate function in XMPFiles/source/FormatSupport/PostScript_Support.cpp

An issue was discovered in Exempi before 2.4.3. The PostScript_Support::ConvertToDate function in XMPFiles/source/FormatSupport/PostScript_Support.cpp allows remote attackers to cause a denial of service (invalid pointer dereference and application crash) via a crafted .ps file.

exempi: Infinite loop in ASF_Support::ReadHeaderObject function in XMPFiles/source/FormatSupport/ASF_Support.cpp

An issue was discovered in Exempi before 2.4.4. The ASF_Support::ReadHeaderObject function in XMPFiles/source/FormatSupport/ASF_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via a crafted .asf file.

exempi: assertion failure in VPXChunk class in XMPFiles/source/FormatSupport/WEBP_Support.cpp

An issue was discovered in Exempi before 2.4.3. The VPXChunk class in XMPFiles/source/FormatSupport/WEBP_Support.cpp does not ensure nonzero widths and heights, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted .webp file.

exempi: Use after free via a PDF file containing JPEG data

An issue was discovered in Exempi before 2.4.3. It allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data, related to XMPFiles/source/FormatSupport/ReconcileTIFF.cpp, XMPFiles/source/FormatSupport/TIFF_MemoryReader.cpp, and XMPFiles/source/FormatSupport/TIFF_Support.hpp.

exempi: Infinite Loop in Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp

An issue was discovered in Exempi before 2.4.4. Integer overflow in the Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .avi file.

kernel: Mishandling mutex within libsas allowing local Denial of Service

The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.

GraphicsMagick: NULL pointer dereference in ReadEnhMetaFile function in coders/emf.c

An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadEnhMetaFile in coders/emf.c, which allows attackers to cause a denial of service via a crafted file.

GraphicsMagick: NULL pointer dereference in ReadCINEONImage function in coders/cineon.c

An issue was discovered in GraphicsMagick 1.3.26. A NULL pointer dereference vulnerability was found in the function ReadCINEONImage in coders/cineon.c, which allows attackers to cause a denial of service via a crafted file.

GraphicsMagick: allocation failure in ReadTIFFImage function in coders/tiff.c

An issue was discovered in GraphicsMagick 1.3.26. An allocation failure vulnerability was found in the function ReadTIFFImage in coders/tiff.c, which allows attackers to cause a denial of service via a crafted file, because file size is not properly used to restrict scanline, strip, and tile allocations.

Remedy Mid Tier in BMC Remedy AR System 9.1 allows XSS via the ATTKey parameter in an arsys/servlet/AttachServlet request.

TitanHQ WebTitan Gateway has incorrect certificate validation for the TLS interception feature.

jabberd: privilege escalation via PID file manipulation

The Gentoo net-im/jabberd2 package through 2.6.1 sets the ownership of /var/run/jabber to the jabber account, which might allow local users to kill arbitrary processes by leveraging access to this account for PID file modification before a root script executes a "kill -TERM `cat /var/run/jabber/filename.pid`" command.

The Gentoo net-im/jabberd2 package through 2.6.1 installs jabberd, jabberd2-c2s, jabberd2-router, jabberd2-s2s, and jabberd2-sm in /usr/bin owned by the jabber account, which might allow local users to gain privileges by leveraging access to this account and then waiting for root to execute one of these programs.

kernel: race condition due to concurrent access to extent tree in fs/ocfs2/aops.c

In the Linux kernel before 4.15, fs/ocfs2/aops.c omits use of a semaphore and consequently has a race condition for access to the extent tree during read operations in DIRECT mode, which allows local users to cause a denial of service (BUG) by modifying a certain e_cpos field.

BMC Remedy AR System before 9.1 SP3, when Remedy AR Authentication is enabled, allows attackers to obtain administrative access.
