Ubuntu 5.04 / 5.10 / 6.06 LTS : gzip vulnerabilities (USN-349-1)

High Nessus Plugin ID 27929


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


Tavis Ormandy discovered that gzip did not sufficiently verify the validity of gzip or compress archives while unpacking. By tricking an user or automated system into unpacking a specially crafted compressed file, this could be exploited to execute arbitrary code with the user's privileges.

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.


Update the affected gzip package.
