Summary
samba vulnerabilities
Details

Sri Nagasubramanian discovered that the Samba acl_xattr VFS module incorrectly handled read-only files. When Samba is configured to ignore system ACLs, a remote attacker could possibly use this issue to truncate read-only files. (CVE-2023-4091)

Andrew Bartlett discovered that Samba incorrectly handled the DirSync control. A remote attacker with an RODC DC account could possibly use this issue to obtain all domain secrets. (CVE-2023-4154)

Andrew Bartlett discovered that Samba incorrectly handled the rpcecho development server. A remote attacker could possibly use this issue to cause Samba to stop responding, resulting in a denial of service. (CVE-2023-42669)

Kirin van der Veer discovered that Samba incorrectly handled certain RPC service listeners. A remote attacker could possibly use this issue to cause Samba to start multiple incompatible RPC listeners, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-42670)
