Description Vincent Danen 2013-04-24 17:29:47 UTC

It was reported [1],[2] that telepathy-idle, an IRC backend for the Telepathy framework, did not check the server's SSL/TLS certificate for validity [3].  This could allow an attacker to carry out man-in-the-middle attacks.

This flaw has existed in the source since 2007, and versions 0.1.11 through to 0.1.14 use GLib for TLS, so they did very basic checks on certificates, but did not check that the certificate issuer was a trusted CA, that the identity matched the server's hostname, or that the certificate had not expired.

The forthcoming 0.1.15 release will fix this flaw; a patch is attached to the upstream bug [4].
