Gentoo Linux Security Advisory

Title: jabberd 1.x: Denial of Service vulnerability (GLSA 200409-31)
Severity: normal
Exploitable: remote
Date: September 23, 2004
Updated: May 22, 2006
Bug(s): #64741
ID: 200409-31

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: net-im/jabberd
Vulnerable: <= 1.4.3-r3
Unaffected: >= 1.4.3-r4
Architectures: All supported architectures


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