> SASL layer length field lacks negative and short-read handling
> --------------------------------------------------------------
>
> Key: DIRAPI-477
> URL: https://issues.apache.org/jira/browse/DIRAPI-477
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.1.8
> Reporter: Emmanuel Lécharny
> Priority: Minor
> Fix For: 2.1.9
>
>
> After a client completes a *SASL* bind with _auth-int_ *QoP*, a *MITM*
> rewrites one *TCP* segment so the 4-byte *SASL* length prefix reads
> _0xFFFFFFFF_; the client's _SaslFilter_ throws _NegativeArraySizeException_
> in the *MINA* chain and the connection dies with a generic error rather than
> an integrity alarm; the peer itself can send the same bytes for a one-packet
> session kill.
