The vulnerabilities are caused due to out-of-bounds read errors within the "sss_autofs_cmd_getautomntent()" and "sss_autofs_cmd_getautomntbyname()" functions in src/responder/autofs/autofssrv_cmd.c and the "ssh_cmd_parse_request()" function in src/responder/ssh/sshsrv_cmd.c, which can be exploited to cause a crash by sending specially crafted packages to SSSD. NOTE: Additionally, a race condition weakness exists when handling directory trees, which can lead to modification of the directory tree. The vulnerabilities are reported in version 1.9.3. Other versions may also be affected. SOLUTION: Fixed in the repository.
