MiracleLinux 4 : ruby-1.8.7.352-4.AXS4 (AXSA:2012-139:02)

high Nessus Plugin ID 284368

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2012-139:02 advisory.

 Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight- forward, and extensible.
 Security issues fixed with this release:
 CVE-2011-4815 Ruby (aka CRuby) before 1.8.7-p357 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected ruby, ruby-irb and / or ruby-libs packages.
