Kerentanan Out-of-bounds Read pada fedoraproject sssd, redhat openshift container platform +1 lainnya. Skor CVSS 3.1 7.1 (High) menurut NVD.

Deskripsi (NVD)

A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service.
