✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: To mitigate this Improper Protection of Alternate Path vulnerability, ensure that secondary execution branches—such as the reuse of cached memory workspaces—enforce the exact same size and boundary checks as the primary memory allocation paths. Limit exposure by preventing untrusted user input from directly controlling PCRE2 regular expressions, and strictly avoid utilizing recursive matching patterns when operating under a low heap limit. Apply a defense-in-depth strategy by validating all inputs comprehensively. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
