Amazon Linux AMI : perl-libwww-perl (ALAS-2011-17)

medium Nessus Plugin ID 69576

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The Net::HTTPS module in libwww-perl (LWP) before 6.00, as used in WWW::Mechanize, LWP::UserAgent, and other products, when running in environments that do not set the If-SSL-Cert-Subject header, does not enable full validation of SSL certificates by default, which allows remote attackers to spoof servers via man-in-the-middle (MITM) attacks involving hostnames that are not properly validated. NOTE: it could be argued that this is a design limitation of the Net::HTTPS API, and separate implementations should be independently assigned CVE identifiers for not working around this limitation. However, because this API was modified within LWP, a single CVE identifier has been assigned.

Solution

Run 'yum update perl-libwww-perl' to update your system.
