medium Nessus Plugin ID 62531

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Some security flaws were found on ruby currently shipped on Fedora 17 where malicious user can bypass safe mechanize by raising exception intentionally and make arbitrary strings tainted. This flaw were now registered as CVE-2012-4464 and CVE-2012-4466.

Note that CVE-2012-4464 is basically the same as CVE-2011-1005, which was supposed to be already fixed on ruby 1.8.x branch but it proved that the fix was incomplete.

This new rpm will fix the above issue.

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

Solution

Update the affected ruby package.
