Debian DLA-407-1 : prosody security update

medium Nessus Plugin ID 88493

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The flaw allows a malicious server to impersonate the vulnerable domain to any XMPP domain whose domain name includes the attacker's domain as a suffix.

For example, 'bber.example' would be able to connect to 'jabber.example' and successfully impersonate any vulnerable server on the network.

This release also fixes a regression introduced in the previous CVE-2016-1232 fix: s2s doesn't work if /dev/urandom is read-only.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected prosody package.
