Debian DLA-224-1 : ruby1.8 security update

medium Nessus Plugin ID 83531

Language:

Synopsis

The remote Debian host is missing a security 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.

For the oldoldstable distribution (squeeze), this problem has been fixed in version 1.8.7.302-2squeeze4.

For the oldstable distribution (wheezy), this problem was fixed in version 1.8.7.358-7.1+deb7u3.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
