Debian DSA-3247-1 : ruby2.1 - security update

medium Nessus Plugin ID 83233

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that the Ruby OpenSSL extension, part of the interpreter for the Ruby language, did not properly implement hostname matching, in violation of RFC 6125. This could allow remote attackers to perform a man-in-the-middle attack via crafted SSL certificates.

Solution

Upgrade the ruby2.1 packages.

For the stable distribution (jessie), this problem has been fixed in version 2.1.5-2+deb8u1.
