Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.15.2 Red Hat Enterprise Linux (affected versions not specified)

Description The issue involves multiple integer overflows in the lzo1x decompress safe function in the LZO decompressor, which can be exploited by context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. The exploitation can be done remotely. However, the author of the LZO algorithms claims that the Linux kernel is not affected.

Recommendations For Linux kernel versions prior to 3.15.2, update to version 3.15.2 or later to resolve the issue. For Red Hat Enterprise Linux, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
