Vulnerability  : TLS verification bypass
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2013-1431

Maksim Otstavnov discovered that the Wocky submodule used by
telepathy-gabble, the Jabber/XMPP connection manager for the Telepathy
framework, does not respect the tls-required flag on legacy Jabber
servers. A network intermediary could use this vulnerability to bypass
TLS verification and perform a man-in-the-middle attack.

For the oldstable distribution (squeeze), this problem has been fixed in
version 0.9.15-1+squeeze2.

For the stable distribution (wheezy), this problem has been fixed in
version 0.16.5-1+deb7u1.

For the testing distribution (jessie) and the unstable distribution
(sid), this problem has been fixed in version 0.16.6-1.
