"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."
