FreeBSD : ejabberd -- mod_muc_occupantid: Fix handling multiple occupant-id (1b8d502e-1cfd-11f0-944d-901b0e9408dc)

high Nessus Plugin ID 234634

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 1b8d502e-1cfd-11f0-944d-901b0e9408dc advisory.

 ejabberd team reports:
 Fixed issue with handling of user provided occupant-id in messages and presences sent to muc room. Server was replacing just first instance of occupant-id with its own version, leaving other ones untouched. That would mean that depending on order in which clients send occupant-id, they could see value provided by sender, and that could be used to spoof as different sender.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
