Descriptions
An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can trigger an out-of-bounds read in Winbind, possibly resulting in a crash.
It was discovered that Samba incorrectly handled Winbind NTLM authentication responses. An attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service. Andreas Schneider discovered that Samba incorrectly enforced SMB2 packet signing. A remote attacker could possibly use this issue to obtain or modify sensitive information. This issue only affected Ubuntu 23.04.
