Ubuntu 4.10 / 5.04 : gzip vulnerability (USN-158-1)

medium Nessus Plugin ID 20562

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

zgrep 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 privileges if zgrep is run in an untrusted directory with specially crafted file names.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected gzip package.
