Mandriva Linux Security Advisory : ruby (MDVSA-2013:124)
Medium Nessus Plugin ID 66136
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated ruby packages fix security vulnerabilities :
Shugo Maedo and Vit Ondruch discovered that Ruby incorrectly allowed untainted strings to be modified in protective safe levels. An attacker could use this flaw to bypass intended access restrictions (CVE-2012-4466, CVE-2012-4481).
It was discovered that Ruby's REXML library did not properly restrict XML entity expansion. An attacker could use this flaw to cause a denial of service by tricking a Ruby application using REXML to read text nodes from specially crafted XML content, which will result in REXML consuming large amounts of system memory (CVE-2013-1821).
SolutionUpdate the affected packages.
