DISPUTED LibTIFF 4.0.8 has multiple memory leak vulnerabilities, which allow attackers to cause a denial of service (memory consumption), as demonstrated by tifopen.c, tiflzw.c, and tifaux.c. NOTE: Third parties were unable to reproduce the issue.

A new exploitation technique called key reinstallation attacks used to break Wi-Fi handshakes that negotiate session keys was discovered. These attacks target the Wi-Fi/WPA2 standard. An adversary can trick a vulnerable Access Point (AP) into reinstalling the pairwise key by retransmitted or replayed FT Reassociation Request. While reinstalling the already in-use key, the associated packet number (sometimes also called nonce) and receive replay counter is reset. This causes nonce reuse, voiding any security the underlying encryption protocol is supposed to provide. For example, it allows decryption or injection of frames, and enables an attacker to replay frames.

A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the heap/stack gap, cause controlled memory corruption on process stack or heap, and thus increase their privileges on the system.

This is a tracking bug for the glibc part of the mitigation.

game-music-emu before 0.6.1 allows remote attackers to generate out of bounds 8-bit values.

game-music-emu before 0.6.1 allows remote attackers to write to arbitrary memory locations.

A vulnerability was found in icoutils in extract.c. It is possible to access unallocated memory via wrestool while parsing maliciously crafted file which would make the application crash or possibly allow code execution.

It also notes some of the issues in bug 630460 may not be fixed correctly.

A fix is currently not available. Fedora and EPEL use a 1.x version. A future 2.0 release may correct these issues: https://code.google.com/p/encfs/issues/detail?id=186
