Kernel: drm/i915: heap writing overflow

Integer overflow in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel through 3.8.3, as used in Google Chrome OS before 25.0.1364.173 and other products, allows local users to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted application that triggers many relocation copies, and potentially leads to a race condition.

httpd: insecure handling of LD_LIBRARY_PATH in envvars

envvars (aka envvars-std) in the Apache HTTP Server before 2.4.2 places a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse DSO in the current working directory during execution of apachectl.

Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, does not properly manage memory during message handling for plug-ins, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Mozilla: Crash when rendering SVG+XSLT (MFSA 2012-08)

Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a malformed XSLT stylesheet that is embedded in a document.

Buffer overflow in the vorbis_parse_setup_hdr_floors function in the Vorbis decoder in vorbisdec.c in libavcodec in FFmpeg through 1.1.3, as used in Google Chrome before 25.0.1364.97 on Windows and Linux and before 25.0.1364.99 on Mac OS X and other products, allows remote attackers to cause a denial of service (divide-by-zero error or out-of-bounds array access) or possibly have unspecified other impact via vectors involving a zero value for a bark map size.

Race condition in Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to media.

Multiple unspecified vulnerabilities in the IPC layer in Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, allow remote attackers to cause a denial of service or possibly have other impact via unknown vectors.

Integer overflow in Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a blob.

Firefox: Ogg Vorbis Decoding Memory Corruption (MFSA 2012-07)

Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 do not properly initialize nsChildView data structures, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Ogg Vorbis file.

Mozilla: memory safety hazards in 10.0/1.9.2.26 (MFSA 2012-01)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

kernel: v4l: VIDIOCSMICROCODE arbitrary write

drivers/media/video/v4l2-compat-ioctl32.c in the Video4Linux (V4L) implementation in the Linux kernel before 2.6.36 on 64-bit platforms does not validate the destination of a memory copy operation, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via a VIDIOCSTUNER ioctl call on a /dev/video device, followed by a VIDIOCSMICROCODE ioctl call on this device.

kernel: arbitrary kernel memory write via i915 GEM ioctl

drivers/gpu/drm/i915/i915_gem.c in the Graphics Execution Manager (GEM) in the Intel i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.36 does not properly validate pointers to blocks of memory, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via crafted use of the ioctl interface, related to (1) pwrite and (2) pread operations.

Multiple unspecified vulnerabilities in the IPC layer in Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, allow remote attackers to cause a denial of service (memory corruption) or possibly have other impact via unknown vectors.

Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, does not properly enforce a user gesture requirement before proceeding with a file download, which might make it easier for remote attackers to execute arbitrary code via a crafted file.

yast2-add-on-creator in SUSE inst-source-utils 2008.11.26 before 2008.11.26-0.9.1 and 2012.9.13 before 2012.9.13-0.8.1 allows local users to gain privileges via a crafted (1) file name or (2) directory name.

Skia, as used in Google Chrome before 25.0.1364.97 on Windows and Linux, and before 25.0.1364.99 on Mac OS X, allows remote attackers to cause a denial of service (out-of-bounds read) via vectors related to a "user gesture check for dangerous file downloads."
