Debian DSA-3159-1 : ruby1.8 - security update

medium Nessus Plugin ID 81279

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that the REXML parser, part of the interpreter for the Ruby language, could be coerced into allocating large string objects that could consume all available memory on the system. This could allow remote attackers to cause a denial of service (crash).

Solution

Upgrade the ruby1.8 packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.8.7.358-7.1+deb7u2.

For the upcoming stable distribution (jessie), this problem has been fixed in version 2.1.5-1 of the ruby2.1 source package.
