CyberRota Analysis
AI-GeneratedA vulnerability exists in the PAM responder's protocol v1 parser within sssd, allowing local clients with access to the UNIX socket to exploit it by sending an empty or truncated PAM request. This can result in an out-of-bounds read, which may cause the PAM responder to crash or restart, leading to a local denial of service. Organizations utilizing sssd for authentication should prioritize addressing this issue to maintain system stability and security.

Original NVD Description
A flaw was found in sssd, specifically within the PAM (Pluggable Authentication Modules) responder's protocol v1 parser, pam_parse_in_data(). A local client with access to the PAM responder's UNIX socket can exploit this by negotiating protocol v1 and sending an empty or truncated PAM request body. This can trigger an out-of-bounds read, potentially causing the PAM responder to terminate or restart, leading to a local denial of service.
