Debian DLA-1967-1 : libpcap security update

medium Nessus Plugin ID 130132

Language:

Synopsis

The remote Debian host is missing a security update.

Description

libpcap (Packet CAPture), a low-level network monitoring library, does not properly validate the PHB header length before allocating memory.
This update added sanity checks for PHB header length.

For Debian 8 'Jessie', this problem has been fixed in version 1.6.2-2+deb8u1.

We recommend that you upgrade your libpcap packages.

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

Solution

Upgrade the affected packages.
