Kerentanan Buffer Access with Incorrect Length Value pada fedoraproject sssd, redhat openshift container platform +1 lainnya. Skor CVSS 3.1 5.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit termination, it results in an out-of-bounds read when processed by functions like snprintf(). A local attacker could potentially trigger this vulnerability by initiating a crafted passkey authentication request, causing the SSSD PAM responder to crash, resulting in a local Denial of Service (DoS).
