CVE-2012-5371

Status Candidate

Overview

Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly 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, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815.

Ubuntu Security Notice USN-1733-1
Posted Feb 21, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1733-1 - Jean-Philippe Aumasson discovered that Ruby incorrectly generated predictable hash values. An attacker could use this issue to generate hash collisions and cause a denial of service. Evgeny Ermakov discovered that documentation generated by rdoc is vulnerable to a cross-site scripting issue. With cross-site scripting vulnerabilities, if a user were tricked into viewing a specially crafted page, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain. Various other issues were also addressed.
