Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptography: Insecure random number generation can lead to predictable SSH keys, compromised key exchanges, and weak cryptographic signatures, completely undermining the security of SSH sessions.
Denial of Service: Failure to reuse and properly close SSH agent connections can result in an accumulation of unclosed file descriptors, eventually exhausting system resources and causing application failure.
