Debian DSA-2074-1 : ncompress - integer underflow

medium Nessus Plugin ID 47792

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Aki Helin discovered an integer underflow in ncompress, the original Lempel-Ziv compress/uncompress programs. This could lead to the execution of arbitrary code when trying to decompress a crafted LZW compressed gzip archive.

Solution

Upgrade the ncompress package.

For the stable distribution (lenny), this problem has been fixed in version 4.2.4.2-1+lenny1.
