info: name:OpenSSH CVE-2024-6409 author:bahlawi89 severity:high description:| A race condition vulnerability was discovered in how signals are handled by OpenSSH's server (sshd). If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). As a consequence of a successful attack, in the worst case scenario, an attacker may be able to perform a remote code execution (RCE) as an unprivileged user running the sshd server. reference: -https://nvd.nist.gov/vuln/detail/CVE-2024-6409 metadata: cve-id:CVE-2024-6409 cvss-score:7.0 verified:true tags:cve,cve2024,openssh,CVE-2024-6409
