Name of the Vulnerable Software and Affected Versions PAN-OS versions 7.1.24 and earlier PAN-OS versions 8.0.19 and earlier PAN-OS versions 8.1.9 and earlier PAN-OS versions 9.0.3 and earlier

Description The issue is caused by a memory corruption vulnerability that allows a remote, unauthenticated user to craft a message to Secure Shell Daemon (SSHD) and corrupt arbitrary memory. This can be achieved by exploiting a buffer overflow operation in memory. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.

Recommendations For PAN-OS versions 7.1.24 and earlier, update to a version later than 7.1.24 to resolve the issue. For PAN-OS versions 8.0.19 and earlier, update to a version later than 8.0.19 to resolve the issue. For PAN-OS versions 8.1.9 and earlier, update to a version later than 8.1.9 to resolve the issue. For PAN-OS versions 9.0.3 and earlier, update to a version later than 9.0.3 to resolve the issue. As a temporary workaround, consider restricting access to the Secure Shell Daemon (SSHD) to minimize the risk of exploitation.
