Jon Siwek of Corelight reports:

+
This is a security patch release to address potential + Denial of Service vulnerabilities:
+
+
+ Null pointer dereference in the RPC analysis code. RPC + analyzers (e.g. MOUNT or NFS) are not enabled in the + default configuration.
+ +
+ Signed integer overflow in BinPAC-generated parser code. + The result of this is Undefined Behavior with respect to + the array bounds checking conditions that BinPAC generates, + so it's unpredictable what an optimizing compiler may + actually do under the assumption that signed integer + overlows should never happen. The specific symptom which + lead to finding this issue was with the PE analyzer causing + out-of-memory crashes due to large allocations that were + otherwise prevented when the array bounds checking logic + was changed to prevent any possible signed integer overlow.
