Mandriva Linux Security Advisory MDVSA-2011:152

_______________________________________________________________________
Package : ncompress
Date : October 17, 2011
Affected: 2010.1, Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
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 4.2.4.4 version which
is not vulnerable to this issue.
