Synopsis
========
The jabberd server was found to be vulnerable to a remote Denial of
Service attack.
Background
==========
Jabber is a set of streaming XML protocols enabling message, presence,
and other structured information exchange between two hosts. jabberd is
the original implementation of the Jabber protocol server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-im/jabberd <= 1.4.3-r3 >= 1.4.3-r4
Description
===========
Jose Antonio Calvo found a defect in routines handling XML parsing of
incoming data. jabberd 1.x may crash upon reception of invalid data on
any socket connection on which XML is parsed.
Impact
======
A remote attacker may send a specific sequence of bytes to an open
socket to crash the jabberd server, resulting in a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All jabberd users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-im/jabberd-1.4.3-r4"
# emerge ">=net-im/jabberd-1.4.3-r4"
