DESCRIPTION:
Multiple vulnerabilities have been reported in SSSD, which can be
exploited by malicious people to cause a DoS (Denial of Service).

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.
