✅ 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 issue, users should avoid processing untrusted or maliciously crafted input with `gawk`. Exercise caution when executing `gawk` scripts or commands that process data from unknown or unverified sources. Workaround: Do not execute untrusted awk scripts or process untrusted inputs that could trigger oversized calculations in builtin.c. Workaround: Do not run gawk against untrusted scripts, files, or directories to prevent triggering these vulnerabilities. If an attack is attempted, Red Hat's built-in memory protections will safely crash the program, preventing malicious code execution.
