Synopsis
========

An integer overflow in LZO might allow remote attackers to execute
arbitrary code or cause a Denial of Service condition.

Background
==========

LZO is an extremely fast compression and decompression library

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-

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”
