USN-2292-1: LWP::Protocol::https vulnerability

17 July 2014

liblwp-protocol-https-perl vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS


LWP::Protocol::https could be made to expose sensitive information over the network.

Software Description

  • liblwp-protocol-https-perl - HTTPS driver for LWP::UserAgent


It was discovered that the LWP::Protocol::https perl module incorrectly disabled peer certificate verification completely when only hostname verification was requested to be disabled. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could possibly be exploited in certain scenarios to alter or compromise confidential information in applications that used the LWP::Protocol::https module.
