golang: crypto/tls: slow verification of certificate chains containing large RSA keys
A denial of service vulnerability was found in the Golang Go package caused by an uncontrolled resource consumption flaw. By persuading a victim to use a specially crafted certificate with large RSA keys, a remote attacker can cause a client/server to expend significant CPU time verifying...
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...
