CyberRota Analysis
AI-GeneratedOpenSSL's Crypt::OpenSSL::X509 versions prior to 2.1.3 are vulnerable to a denial of service due to a NULL pointer dereference when handling certain certificate extensions. This flaw can lead to a SIGSEGV crash of the Perl process if an untrusted certificate is processed, impacting applications relying on this library. Organizations using affected versions should prioritize patching to mitigate potential disruptions in service.

Original NVD Description
Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow denial of service via NULL pointer dereference. X509V3_EXT_d2i(ext) returns NULL when an extension's DER value fails to parse. basicC, ia5string, and auth_att dereference its result without a NULL check. keyid_data also dereferences akid->keyid, which is NULL for an empty AKI SEQUENCE (DER 30 00) even when the parse succeeds. A caller invoking an affected helper on an extension from an untrusted certificate triggers a SIGSEGV that crashes the Perl process.
