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"
