Security #6195: process exit in hyperscan error handling

Added by Victor Julien almost 3 years ago. Updated over 2 years ago.

Status:
Closed
Priority:
Normal
Assignee:
Victor Julien
Target version:
7.0.1
Affected Versions:
Label:
CVE:
Git IDs:
Severity:
HIGH
Disclosure Date:

Description

A malformed rule can cause the process to exit due to hyperscan integration triggering a fatal error if hyperscan can't compile a pattern.

This can happen during a rule upgrade, which would exit the process. The process could then not start back up again until the offending rule is removed.

The issue would be mitigated by using a "test" step in the rule upgrade process. In this case the ruleset update would be rejected.

I'll take a look at this; can you share the rule that causes hs compilation to fail?
