Debian DSA-2074-1 : ncompress - integer underflow

medium Nessus Plugin ID 47792

Language:

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.
