CVE-2026-58102
Crypt::OpenSSL::X509 versions before 2.1.3 for Perl allow a heap out-of-bounds read via a long certificate extension OID in hvexts. When building the extension hash via extensions, extensionsbylongname, extensionsbyoid, or hasextensionoid, the code passes OBJobj2txt's return value as the hash-key...
