Mandriva Linux Security Advisory : ncompress (MDVSA-2011:152)

Medium Nessus Plugin ID 56530


The remote Mandriva Linux host is missing a security update.


A vulnerability has been found and corrected in ncompress :

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).

The updated packages have been upgraded to the version which is not vulnerable to this issue.


Update the affected ncompress package.
