The jabberd server was found to be vulnerable to a remote Denial of Service attack.

2.  Impact Information


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.


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.


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.

3.  Resolution Information


There is no known workaround at this time.


All jabberd users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge sync

# emerge -pv ">=net-im/jabberd-1.4.3-r4"
# emerge ">=net-im/jabberd-1.4.3-r4"
