Mandriva Linux Security Update Advisory
_______________________________________________________________________

Package name: gzip
Advisory ID: MDKSA-2005:092
Date: May 18th, 2005

Affected versions: 10.0, 10.1, 10.2, Corporate 3.0,
Corporate Server 2.1
______________________________________________________________________

Problem Description:

Several vulnerabilities have been discovered in the gzip package:

Zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script. (CAN-2005-0758)

A race condition in gzip 1.2.4, 1.3.3, and earlier when decompressing a gzip file allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete. (CAN-2005-0988)

A directory traversal vulnerability via "gunzip -N" in gzip 1.2.4 through 1.3.5 allows remote attackers to write to arbitrary directories via a .. (dot dot) in the original filename within a compressed file. (CAN-2005-1228)

Updated packages are patched to address these issues.
