Red Hat Enterprise Linux 10: Incorrect Authorization
A flaw was found in libssh. On servers with GSSAPIKeyExchange enabled, the gssapi-keyex path does not verify whether the authenticated Kerberos principal is authorized for the requested local user, allowing authenticated clients to log in as arbitrary users.
- 7.5 High severity
Red Hat Enterprise Linux 10: Use After Free
A flaw was found in libssh. If data packets are processed after a channel is closed, channel data callbacks can be invoked after the associated data has already been freed, leading to crashes or possible use-after-free conditions.
- 7.5 High severity
Red Hat Enterprise Linux 10: Loop with Unreachable Exit Condition
A flaw was found in libssh. Logic errors in automatic certificate-based public key authentication can cause libssh clients to loop indefinitely when configured certificates are missing or repeatedly rejected by a server, leading to denial of service.
- 7.5 High severity
