Ubuntu 16.04 LTS / 18.04 LTS : libpcap vulnerability (USN-4221-1)

medium Nessus Plugin ID 132016

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

It was discovered that libpcap did not properly validate PHB headers in some situations. An attacker could use this to cause a denial of service (memory exhaustion).

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 libpcap-dev, libpcap0.8 and / or libpcap0.8-dev packages.
