Description
The issue allows remote attackers to disclose sensitive information or cause a denial of service (application crash) via a crafted regular expression with an invalid 'N{U+...}' escape in the S grok bslash N function in regcomp.c.
Recommendations
For versions prior to 5.24.3-RC1, update to version 5.24.3-RC1 or later.
