jabberd 1.x: Denial of Service vulnerability

jabberd 1.x: Denial of Service vulnerability The jabberd server was found to be vulnerable to a remote Denial of Service attack. jabberd 2004-09-23 2006-05-22 64741 remote 1.4.3-r4 1.4.3-r3

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:


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