CVE [?]: CVE-2012-6329
CPE [?]: cpe:/o:fedoraproject:fedora:17, p-cpe:/a:fedoraproject:fedora:perl

Synopsis

The remote Fedora host is missing a security update.

Description

Fix double-free when loading Digest::SHA object representing the intermediate SHA state from a file (RT#82655)

The following command should be run without any errors.

perl -MDigest::SHA -e 'my $d = Digest::SHA->new(256); $d->load('x');' Fix Locale::Maketext vulnerability allowing to cross-call functions from message catalogs (CVE-2012-6329).

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 perl package.
