New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Mandriva Linux host is missing a security update.

Description

Multiple vulnerabilities has been found and corrected in gzip :

A missing input sanitation flaw was found in the way gzip used to decompress data blocks for dynamic Huffman codes. A remote attacker could provide a specially crafted gzip compressed data archive, which once opened by a local, unsuspecting user would lead to denial of service (gzip crash) or, potentially, to arbitrary code execution with the privileges of the user running gzip (CVE-2009-2624).

An integer underflow leading to array index error was found in the way gzip used to decompress files / archives, compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. A remote attacker could provide a specially crafted LZW compressed gzip archive, which once decompressed by a local, unsuspecting user would lead to gzip crash, or, potentially to arbitrary code execution with the privileges of the user running gzip (CVE-2010-0001).

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers.

The updated packages have been patched to correct these issues.

Solution

Update the affected gzip package.
