MDKSA-2005:092: gzip

Vulnerability Assessment Summary
Check for the version of the gzip package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2005:092 (gzip).

Several vulnerabilities have been discovered in the gzip package:

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

A race condition in gzip 1.2.4, 1.3.3, and earlier when decompressing a gzip
file permits 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. (CVE-2005-0988)

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

Updated packages are patched to address these issues.
