May 9, 2023 update: Releases for Microsoft Products has been updated with the release of CVE-2023-29324 - Security Update Guide - Microsoft - Windows MSHTML Platform Security Feature Bypass Vulnerability March 24, 2023 update: Impact Assessment has been updated to a link to Guidance for investigating attacks using CVE-2023-23397 - Microsoft Security Blog.

Ubuntu Security Notice 5936-1 - Evgeny Legerov discovered that Samba incorrectly handled buffers in certain GSSAPI routines of Heimdal. A remote attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service. Tom Tervoort discovered that Samba incorrectly used weak rc4-hmac Kerberos keys. A remote attacker could possibly use this issue to elevate privileges.

Red Hat Security Advisory 2023-1090-01 - Samba is an open-source implementation of the Server Message Block protocol and the related Common Internet File System protocol, which allow PC-compatible machines to share files, printers, and various information.

An update for samba is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important.

Related CVEs: * CVE-2022-38023: A flaw was found in samba. The Netlogon RPC implementations may use the rc4-hmac encryption algorithm, which is considered weak and should be avoided even if the client supports more modern encryption types. This issue could allow an attacker who knows the plain text content communicated between the samba client and server to craft data with the s...

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).

A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met.

The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to be inverted.

An issue was discovered in Docmosis Tornado prior to version 2.9.5. An authenticated attacker can change the Office directory setting pointing to an arbitrary remote network path. This triggers the execution of the soffice binary under the attackers control leading to arbitrary remote code execution (RCE).
