Debian DLA-1951-1 : libtomcrypt security update

critical Nessus Plugin ID 129765

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a denial of service vulnerability in the libtomcrypt cryptographic library.

An out-of-bounds read and crash could occur via carefully-crafted 'DER' encoded data (eg. by importing an X.509 certificate).

For Debian 8 'Jessie', this issue has been fixed in libtomcrypt version 1.17-6+deb8u1.

We recommend that you upgrade your libtomcrypt 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 libtomcrypt-dev, and libtomcrypt0 packages.
