Ubuntu 14.04 LTS / 16.04 LTS / 17.10 / 18.04 LTS : zziplib vulnerabilities (USN-3699-1)

Medium Nessus Plugin ID 110921

Synopsis

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

Description

It was discovered that zziplib incorrectly handled certain malformed ZIP files. If a user or automated system were tricked into opening a specially crafted ZIP file, a remote attacker could cause zziplib to crash, resulting in a denial of service, or possibly execute arbitrary code.

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 libzzip-0-13 package.
