Summary
python-asyncssh vulnerabilities
Details

Fabian Bäumer, Marcus Brinkmann, and Jörg Schwenk discovered that the SSH protocol was vulnerable to a rogue extension negotiation attack. If a remote attacker was able to intercept SSH communications, extension info message could be replaced, possibly leading to certain algorithms and features being downgraded.
