Laurent Gaffié has reported a vulnerability in Novell NetWare, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in CIFS.NLM when processing SMB packets. This can be exploited to cause a stack-based buffer overflow via a "Session Setup AndX" SMB packet containing an overly long "AccountName".

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 6.5 SP8. Prior versions may also be affected.

Apply vendor patch.
