Debian DLA-861-1 : r-base security update

high Nessus Plugin ID 97798

Language:

Synopsis

The remote Debian host is missing a security update.

Description

An exploitable buffer overflow vulnerability exists in the LoadEncoding functionality of the R programming language. A specially crafted R script can cause a buffer overflow resulting in a memory corruption. An attacker can send a malicious R script to trigger this vulnerability.

For Debian 7 'Wheezy', this problem has been fixed in version 2.15.1-4+deb7u1.

We recommend that you upgrade your r-base 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.
