GLSA 201701-14: LZO: Multiple vulnerabilities

Severity:normal
Title:LZO: Multiple vulnerabilities
Date:01/02/2017
Bugs: #515238
ID:201701-14

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 Architecture(s)
dev-libs/lzo < 2.08 >= 2.08 All supported architectures

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"
