[Secure-testing-team] Bug#492434: pidgin: Connects to Jabber server with bad SSL certificates without warning

[Josh Triplett]

Package: pidgin
Version: 2.4.3-1
Severity: grave
Tags: security
Justification: user security hole

I recently set up a Jabber server.  I used the default snakeoil
certificate.  When I configured Pidgin to connect to my new server,
using SSL, it connected without any complaint whatsoever.
