MDKSA-2005:092: gzip Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the gzip package
Detailed Explanation for this Vulnerability Test
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 allows
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 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. (CVE-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. (CVE-2005-1228)
Updated packages are patched to address these issues.
