Mandriva Linux Security Advisory 2010-019 - 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. The updated packages have been patched to correct this issue.
