HP Security Bulletin HPSBHF03271 1

HP Security Bulletin HPSBHF03271 1 – A potential security vulnerability has been identified with certain HP PCs and workstations running Windows 7 and NVidia Graphics Driver. This vulnerability could be exploited resulting in elevation of privilege. Note: The NVIDIA Display Drivers kernel administrator check improperly validates local client impersonation levels in some cases. Revision 1 of this advisory.

Mandriva Linux Security Advisory 2015-184

Mandriva Linux Security Advisory 2015-184 – An issue has been identified in Mandriva Business Server 2’s setup package where the /etc/shadow and /etc/gshadow files containing password hashes were created with incorrect permissions, making them world-readable. This update fixes this issue by enforcing that those files are owned by the root user and shadow group, and are only readable by those two entities. Note that this issue only affected new Mandriva Business Server 2 installations. Systems that were updated from previous Mandriva versions were not affected.

Mandriva Linux Security Advisory 2015-159

Mandriva Linux Security Advisory 2015-159 – Josh Duart of the Google Security Team discovered heap-based buffer overflow flaws in JasPer, which could lead to denial of service or the execution of arbitrary code. A double free flaw was found in the way JasPer parsed ICC color profiles in JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code. A heap-based buffer overflow flaw was found in the way JasPer decoded JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code. An off-by-one flaw, leading to a heap-based buffer overflow, was found in the way JasPer decoded JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code. An unrestricted stack memory use flaw was found in the way JasPer decoded JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash or, possibly, execute arbitrary code.

Mandriva Linux Security Advisory 2015-145-1

Mandriva Linux Security Advisory 2015-145 – Ilja van Sprundel discovered that libXfont incorrectly handled font metadata file parsing. A local attacker could use this issue to cause libXfont to crash, or possibly execute arbitrary code in order to gain privileges. Ilja van Sprundel discovered that libXfont incorrectly handled X Font Server replies. A malicious font server could return specially-crafted data that could cause libXfont to crash, or possibly execute arbitrary code. The bdf parser reads a count for the number of properties defined in a font from the font file, and allocates arrays with entries for each property based on that count. It never checked to see if that count was negative, or large enough to overflow when multiplied by the size of the structures being allocated, and could thus allocate the wrong buffer size, leading to out of bounds writes. If the bdf parser failed to parse the data for the bitmap for any character, it would proceed with an invalid pointer to the bitmap data and later crash when trying to read the bitmap from that pointer. The bdf parser read metrics values as 32-bit integers, but stored them into 16-bit integers. Overflows could occur in various operations leading to out-of-bounds memory access.

Mandriva Linux Security Advisory 2015-180

Mandriva Linux Security Advisory 2015-180 – apache-mod_wsgi before 4.2.4 contained an off-by-one error in applying a limit to the number of supplementary groups allowed for a daemon process group. The result could be that if more groups than the operating system allowed were specified to the option supplementary-groups, then memory corruption or a process crash could occur. It was discovered that mod_wsgi incorrectly handled errors when setting up the working directory and group access rights. A malicious application could possibly use this issue to cause a local privilege escalation when using daemon mode.
