patches/packages/samba-4.15.13-x86_64-1_slack15.0.txz: Upgraded. This update fixes security issues: This is the Samba CVE for the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability disclosed by Microsoft on Nov 8 2022. A Samba Active Directory DC will issue weak rc4-hmac session keys for use between modern clients and servers despite all modern Kerberos implementations supporting the aes256-cts-hmac-sha1-96 cipher. On Samba Active Directory DCs and members 'kerberos encryption types = legacy' would force rc4-hmac as a client even if the server supports aes128-cts-hmac-sha1-96 and/or aes256-cts-hmac-sha1-96. This is the Samba CVE for the Windows Kerberos Elevation of Privilege Vulnerability disclosed by Microsoft on Nov 8 2022. A service account with the special constrained delegation permission could forge a more powerful ticket than the one it was presented with. The "RC4" protection of the NetLogon Secure channel uses the same algorithms as rc4-hmac cryptography in Kerberos, and so must also be assumed to be weak. Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96). Note that there are several important behavior changes included in this release, which may cause compatibility problems interacting with system still expecting the former behavior. Please read the advisories of CVE-2022-37966, CVE-2022-37967 and CVE-2022-38023 carefully!
