LZO: Multiple vulnerabilities

Background

LZO is an extremely fast compression and decompression library

Description

LZO is vulnerable to an integer overflow condition in the “lzo1x_decompress_safe” function which could result in a possible buffer overrun when processing maliciously crafted compressed input data.

Impact

A remote attacker could send specially crafted compressed input data possibly resulting in a Denial of Service condition or arbitrary code execution.

Workaround

There is no known workaround at this time.

Resolution

All LZO users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-libs/lzo-2.08"
