CVE-2012-2110: The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and...

Security readout for executives and security teams

CVE-2012-2110 is an OpenSSL parsing flaw where specially crafted certificate or public-key data can corrupt memory. For executives, the main concern is legacy systems still running old OpenSSL builds. The source bundle does not show CISA KEV listing or confirmed active exploitation. Exposure is most likely in old Linux, appliance, embedded, or vendor-bundled software using affected OpenSSL versions. Modern supported systems are less likely exposed unless they retain legacy OpenSSL libraries or statically linked applications. Prioritize remediation if any legacy OpenSSL-dependent service is internet-facing or processes untrusted certificates or keys. For fully supported, patched fleets, urgency is mainly audit-driven because this is an old vulnerability with no KEV evidence in the bundle. Mitigation focus: Upgrade OpenSSL to 0.9.8v, 1.0.0i, 1.0.1a, or vendor-patched packages.; Prioritize internet-facing TLS, certificate-processing, VPN, mail, and appliance components.; Inventory statically linked applications that may bundle vulnerable OpenSSL code..
