It was discovered that the Invariance Weakness of the RC4 stream cipher could be used to recover plaintext from a TLS connection, when RC4 encryption is used.
"The Invariance Weakness is an L-shape key pattern in RC4 keys, which once it exists in an RC4 key, preserves part of the state permutation intact throughout the initialization process. This intact part includes the least significant bits of the permutation, when processed by the PRGA algorithm, determines the least significant bits of the allegedly pseudo-random output stream along a long prefix of the stream."
This can lead to significant leakage of plaintext bytes from the ciphertext.

An information leak vulnerability in rtnetlink subsystem in Linux kernel was found in "net/core/rtnetlink.c". The stack object "map" has a total size of 32 bytes. Its last 4 bytes are padding generated by compiler. These padding bytes are not initialized and sent out via nlaput().

arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x8664 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.
Buffer overflow in the utilpathencode function in udev/lib/libudev-util.c in udev before 1.4.1 allows local users to cause a denial of service (service outage) via vectors that trigger a call with crafted arguments.
Qemu emulator built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing transmit descriptor data when sending a network packet.
A privileged user inside guest could use this flaw to crash the Qemu instance resulting in DoS.
