Title:	Ubuntu: Security Advisory (USN-6425-2)
Summary:	The remote host is missing an update for the 'samba' package(s) announced via the USN-6425-2 advisory.
Description:	Summary: The remote host is missing an update for the 'samba' package(s) announced via the USN-6425-2 advisory. Vulnerability Insight: USN-6425-1 fixed vulnerabilities in Samba. Due to a build issue on Ubuntu 20.04 LTS, the update introduced regressions in macro handling and possibly other functionality. This update fixes the problem. We apologize for the inconvenience. Original advisory 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) Affected Software/OS: 'samba' package(s) on Ubuntu 20.04. Solution: Please install the updated package(s).
