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.

    Thanks to Chris Hinshaw for reporting the issue.
