Authentication flaw

wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a result, it was possible to combine DTLS messages using different keys into one DTLS record. The most extreme edge case is that, in DTLS 1.3, it was possible that an unencrypted DTLS 1.3 record...

CVE-2023-6937

Summary: CVE-2023-6937 affects wolfSSL prior to 5.6.6, where messages within a single (D)TLS record were not checked for crossing key boundaries. This allows combining messages encrypted under different keys into one record, with a notable edge case in (D)TLS 1.3 where an unencrypted server fligh...

wolfSSL 安全漏洞

wolfSSL CyaSSL is the United States wolfSSL company for embedded systems developers to use a small, portable embedded SSL programming library. An input validation error vulnerability exists in WolfSSL versions prior to 5.6.6, which stems from a failure to check if a message crosses a key boundary...

Observable Discrepancy

Overview Affected versions of this package are vulnerable to Observable Discrepancy due to the implementation of the SP Math All RSA when built with specific configuration options. An attacker can decrypt ciphertexts and forge signatures after probing with a large number of test observations...
