A privilege escalation flaw was found in the way udev used to check for the origin of messages sent from the NETLINK service. An attacker could use this flaw to escalate his privileges by sending the NETLINK message from userspace process, instead of from the kernel.

Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for responsibly reporting this flaw.

Integer overflow in exif.cpp in exiv2 library allows context-dependent attackers to execute arbitrary code via a crafted EXIF file that triggers a heap-based buffer overflow.

Multiple integer overflows in PHP 4 before 4.4.8, and PHP 5 before 5.2.4, allow remote attackers to obtain sensitive information (memory contents) or cause a denial of service (thread crash) via a large len value to the (1) strspn or (2) strcspn function, which triggers an out-of-bounds read. NOTE: this affects different product versions than CVE-2007-3996.

Buffer overflow in the safernamesuffix function in GNU tar has unspecified attack vectors and impact, resulting in a "crashing stack."

The Zend Engine in PHP 4.x before 4.4.7, and 5.x before 5.2.2, allows remote attackers to cause a denial of service (stack exhaustion and PHP crash) via deeply nested arrays, which trigger deep recursion in the variable destruction routines.
