CVE-2023-29409 Large RSA keys can cause high CPU usage in crypto/tls

Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to = 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three...

MD5 vulnerable to collision attacks

Overview Weaknesses in the MD5 algorithm allow for collisions in output. As a result, attackers can generate cryptographic tokens or other data that illegitimately appear to be authentic. Description A secure cryptographic hash algorithm is one that generates a unique identifier of a fixed size...
