USN161-1 : bzip2 vulnerability

Vulnerability Assessment Summary
bzip2 vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- bzip2
- libbz2-1.0
- libbz2-dev

Description :

USN-158-1 fixed a command injection vulnerability in the "zgrep"
utility. It was acertaind that the "bzgrep" counterpart in the bzip2
package is vulnerable to the same flaw.

bzgrep did not handle shell metacharacters like '|' and '&' properly
when they occurred in input file names. This could be exploited to
execute arbitrary commands with user rights if bzgrep was run in
an untrusted directory with specially crafted file names.

Solution :

Upgrade to :
- bzip2-1.0.2-2ubuntu0.2 (Ubuntu 5.04)
- libbz2-1.0-1.0.2-2ubuntu0.2 (Ubuntu 5.04)
- libbz2-dev-1.0.2-2ubuntu0.2 (Ubuntu 5.04)
