CVE-2023-6936
The vulnerability CVE-2023-6936 affects wolfSSL prior to 5.6.6, where enabling callbacks (WOLFSSL_CALLBACKS) can cause a 5-byte heap buffer over-read by a malicious TLS client or network attacker. Root cause is the use of WOLFSSL_CALLBACKS for debugging; impact is confidentiality/availability con...

wolfSSL 缓冲区错误漏洞
wolfSSL CyaSSL is the United States wolfSSL company for embedded systems developers to use a small, portable embedded SSL programming library. A security vulnerability exists in wolfSSL versions prior to 5.6.6, which can be exploited by an attacker to trigger a 5-byte buffer out-of-bounds read...
Marvin Attack
Overview Affected versions of this package are vulnerable to Marvin Attack due to the improper handling of DTLS records that do not check if messages span key boundaries. An attacker can exploit this vulnerability to combine DTLS messages using different keys into one DTLS record. Notes: 1 An...
DEBIAN-CVE-2023-6937
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...
