CyberRota Analysis
AI-GeneratedOpenSSL versions prior to 2.1.3 for Perl are vulnerable to a heap out-of-bounds read due to improper handling of long certificate extension OIDs, which can lead to exposure of adjacent heap memory. This critical vulnerability, with a CVSS score of 9.1, poses significant risks, including potential information disclosure. Organizations utilizing affected versions of OpenSSL should prioritize immediate updates to mitigate the risk of exploitation.

Original NVD Description
Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow a heap out-of-bounds read via a long certificate extension OID in hv_exts. When building the extension hash (via extensions(), extensions_by_long_name(), extensions_by_oid(), or has_extension_oid()), the code passes OBJ_obj2txt()'s return value as the hash-key length; because that value is the OID's full text length rather than the bytes written to the fixed-size buffer (129 bytes), an OID whose text is longer than the 129-byte buffer causes a read past the allocation, exposing adjacent heap memory as the returned hash key. extensions_by_name() uses the static shortname path and is not affected.
