The expat XML parser in the aprxml interface in xml/aprxml.c in Apache APR-util before 1.3.7, as used in the moddav and moddavsvn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, as demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564.
src/tools/pkcs11-tool.c in pkcs11-tool in OpenSC 0.11.7, when used with unspecified third-party PKCS#11 modules, generates RSA keys with incorrect public exponents, which allows attackers to read the cleartext form of messages that were intended to be encrypted.
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.

The Device Mapper multipathing driver (aka multipath-tools or device-mapper-multipath) 0.4.8, as used in SUSE openSUSE, SUSE Linux Enterprise Server (SLES), Fedora, and possibly other operating systems, uses world-writable permissions for the socket file (aka /var/run/multipathd.sock), which allows local users to send arbitrary commands to the multipath daemon.
Heap-based buffer overflow in pcrecompile.c in the Perl-Compatible Regular Expression (PCRE) library 7.7 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a regular expression that begins with an option and contains multiple branches.
Multiple heap-based buffer overflows in the cirrusinvalidateregion function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
