Scientific Linux Security Update : ruby on SL5.x, SL6.x i386/srpm/x86_64

Medium Nessus Plugin ID 68946


The remote Scientific Linux host is missing one or more security updates.


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.


Update the affected packages.
