FreeBSD : krb5 -- ASN.1 decoder denial-of-service vulnerability (bd60922b-fb8d-11d8-a13e-000a95bc6fae)

Medium Nessus Plugin ID 36731


The remote FreeBSD host is missing a security-related update.


An advisory published by the MIT Kerberos team says :

The ASN.1 decoder library in the MIT Kerberos 5 distribution is vulnerable to a denial-of-service attack causing an infinite loop in the decoder. The KDC is vulnerable to this attack.

An unauthenticated remote attacker can cause a KDC or application server to hang inside an infinite loop.

An attacker impersonating a legitimate KDC or application server may cause a client program to hang inside an infinite loop.


Update the affected package.
