DESCRIPTION:
Fedora has issued an update for perl-libwww-perl. This fixes a
weakness, which can be exploited by malicious people to bypass
certain security features.

The weakness is caused due to lwp-download not properly checking
filenames suggested via the "Content-Disposition" header when
downloading files from an HTTP server. By suggesting a different
filename than expected by the user, this can be exploited to e.g.
overwrite hidden files in the current directory on a user's system by
tricking the user into downloading a file with a seemingly harmless
filename from a malicious HTTP server.

SOLUTION:
Apply updated packages using the yum utility ("yum update
perl-libwww-perl").
