CVE-2012-0884: The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL before 0.9.8u and 1.x befor...

Security readout for executives and security teams

This is an old OpenSSL cryptography bug. In vulnerable versions, CMS/PKCS #7 encrypted data handling could leak enough oracle behavior for a context-dependent attacker to make decryption easier through a Million Message Attack. Business risk is highest where legacy OpenSSL still processes encrypted CMS/PKCS #7 content. Exposure is most plausible in legacy systems, appliances, or applications that still use affected OpenSSL versions for CMS or PKCS #7 encrypted message handling. The bundle lists multiple vendor advisories, implying packaged downstream exposure, but does not enumerate exact affected products in structured form. Treat this as a legacy exposure cleanup item unless affected cryptographic processing is internet-facing or handles untrusted encrypted content. It should be remediated through standard patch and asset hygiene, with higher priority for unsupported systems or embedded products. Mitigation focus: Upgrade OpenSSL to 0.9.8u, 1.0.0h, or a vendor-fixed package.; Review Red Hat, Fedora, Debian, SUSE, IBM, Avaya, or HP guidance where applicable.; Inventory legacy appliances and bundled software that may carry old OpenSSL libraries..
