CVE-2002-1824

Microsoft Internet Explorer 6.0, when handling an expired CA-CERT in a webserver's certificate chain during a SSL/TLS handshake, does not prompt the user before searching for and finding a newer certificate, which may allow attackers to perform a man-in-the-middle attack. NOTE: it is not clear...

golang: crypto/tls: lack of a limit on buffered post-handshake

A flaw was found in Golang. QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With the fix, connections now consistently reject messages larger than 65KiB in size...

golang: crypto/tls: panic when processing post-handshake message on QUIC connections

A flaw was found in Golang. Processing an incomplete post-handshake message for a QUIC connection caused a panic...
