Mandriva Linux Security Advisory : ruby (MDVSA-2013:201)
Medium Nessus Plugin ID 69089
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA vulnerability has been discovered and corrected in ruby :
A flaw was found in Ruby's SSL client's hostname identity check when handling certificates that contain hostnames with NULL bytes. An attacker could potentially exploit this flaw to conduct man-in-the-middle attacks to spoof SSL servers. Note that to exploit this issue, an attacker would need to obtain a carefully-crafted certificate signed by an authority that the client trusts (CVE-2013-4073).
The updated packages have been patched to correct this issue.
SolutionUpdate the affected packages.
