jabberd 1.x: Denial of Service vulnerability
Gentoo Linux Security Advisory
||GLSA 200409-31 / jabberd
||September 23, 2004
||May 22, 2006: 02
All supported architectures
The jabberd server was found to be vulnerable to a remote Denial of Service
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.
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"
