✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this issue, avoid processing untrusted PKCS#12 files. Applications should only handle PKCS#12 files from trusted sources, as these files are typically used for storing private keys and are expected to be secure. 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. Workaround: To mitigate this issue, avoid using the `openssl dgst` command with one-shot algorithms (such as Ed25519, Ed448, or ML-DSA) for files larger than 16MB. Instead, utilize streaming digest algorithms with `openssl dgst` or use library APIs for signing and verification, as these are not affected by the truncation vulnerability. Users should ensure that input files for one-shot signing/verification with `openssl dgst` do not exceed 16MB. Workaround: To mitigate this issue, disable the reception of compressed certificates by setting the SSL_OP_NO_RX_CERTIFICATE_COMPRESSION option in OpenSSL configurations. This will prevent the vulnerable code path from being exercised. Workaround: To mitigate this vulnerability, Red Hat recommends avoiding the processing of PKCS#12 files from untrusted or unverified sources. Applications that use the `PKCS12_get_friendlyname()` API should ensure that PKCS#12 files are only processed if they originate from trusted entities. Restricting the input sources for PKCS#12 files can significantly reduce the attack surface for this flaw. Workaround: Restrict applications from processing untrusted or externally supplied PKCS#12 files, ensuring certificates are sourced only from trusted internal authorities. Additionally, configure critical background services with automatic restart policies (such as systemd's Restart=on-failure) to quickly restore availability if a denial-of-service crash occurs.
