Description

Jon Siwek of Corelight reports:

This is a security patch release to address a potential

Denial of Service vulnerability:

The NTLM analyzer did not properly handle AV Pair sequences

that were either empty or unterminated, resulting in

invalid memory access or heap buffer over-read. The NTLM

analyzer is enabled by default and used in the analysis

of SMB, DCE/RPC, and GSSAPI protocols.
