Doc Text:
A flaw was found in the SSH Agent servers component (golang.org/x/crypto/ssh/agent). This vulnerability allows a remote attacker to cause a denial of service (DoS) by sending a specially crafted, malformed message during new identity requests. The server fails to validate the size of these messages, leading to an out-of-bounds read that can cause the program to panic and terminate.

Description OSIDB Bzimport 2025-11-19 21:01:33 UTC 
SSH Agent servers do not validate the size of messages when processing new identity requests, which may cause the program to panic if the message is malformed due to an out of bounds read.
