                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.
