Answer in brief
CVE-2024-6387 records a Unknown severity vulnerability in Openssh: regresshion - race condition in ssh allows rce/dos. The current sources do not mark it as known exploited. The current feed maps Siemens/Industrial Edge Management OS (IEM-OS) (generic), Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP (generic), Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP (generic), Siemens/SINAMICS IIoT module (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
