The issue lies in the packet handling routines, where improper bounds checking allows an attacker to send a specially crafted sequence of packets to overflow a buffer. The flaw, discovered by researchers at Qualys in May 2024, and assigned the identifier CVE-2024-6387, is due to a signal handler race condition in sshd that allows unauthenticated remote attackers to execute arbitrary code as root. We have to create our own SSH keys and This vulnerability is exploitable remotely on glibc-based Linux systems, where syslog() itself calls async-signal-unsafe functions (for example, malloc() and free()): an unauthenticated remote code execution as root, because it affects sshd's privileged code, which is not sandboxed and runs with full privileges.
