openCryptoki: openCryptoki: Information disclosure and Denial of Service via malformed BER-encoded cryptographic objects

A flaw was found in openCryptoki, a PKCS11 Cryptographic Token Interface Standard library. The BER/DER Basic Encoding Rules/Distinguished Encoding Rules decoding functions in the shared common library do not properly validate attacker-controlled length fields against actual buffer boundaries. Thi...
