✅ Remediation
The Insights proxy container image provided here is downloaded by the Red Hat Insights proxy product RPM. Before applying this update, make sure all previously released errata relevant to your system have been applied. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Applying the upstream patch or vendor-supplied security update is the recommended resolution. Workaround: To mitigate this issue, consider refactoring the use of the wordexp function to not use the WRDE_REUSE and WRDE_APPEND flags together. Workaround: Applications calling one of the vulnerable functions and allowing the alignment parameter to be set by user-controlled input can implement additional validations checks, ensuring the alignment value is a power of two and does not exceed a sane limit, for example the system page size or a maximum of 64KB. This prevents the excessively large value required to trigger the integer overflow. 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.
