Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) Out-of-bounds read

EUVDB-ID: #VU78577

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2127

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information or perform denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in winbindd_pam_auth_crap.c in winbind AUTH_CRAP when performing NTLM authentication. A remote attacker can trigger an out-of-bounds read error and gain access to sensitive information or crash the server.

Mitigation

Update the affected package samba to the latest version.
