medium Nessus Plugin ID 66792

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the telepathy-gabble packages.

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.
