Jabberd SASL Negotiation Denial of Service Vulnerability Vulnerability Scan
Vulnerability Scan Summary
Tries to crash jabberd c2s component
Detailed Explanation for this Vulnerability Test
Synopsis :
The remote instant messaging server is affected by a denial of service
issue.
Description :
The remote host is running jabberd, an open-source messaging system
based on the Jabber protocol.
The version of jabberd installed on the remote host suffers a segfault
when a client sends a SASL 'response' stanza before a SASL 'auth'
stanza. An unauthenticated remote attacker can leverage this flaw to
crash the application's c2s component, thereby denying service to
legitimate users.
