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

Ubuntu Security Notice USN-2292-1

17th 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.
