      <Note Type="Summary" Ordinal="001">An update for samba is now available for HCE 2.0

HCE Security has rated this update as having a security impact of Important.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
      <Note Type="General" Ordinal="002">Security Fix(es):

In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. (CVE-2022-1615)

A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling full domain takeover. (CVE-2022-32744)

A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

Samba does not validate the Validated-DNS-Host-Name right for the dNSHostName attribute which could permit unprivileged users to write it. (CVE-2022-32743)

A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a single account and set of keys, allowing them to decrypt each other's tickets. A user who has been requested to change their password, can exploit this flaw to obtain and use tickets to other services. (CVE-2022-2031)

A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). (CVE-2022-32742)

A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)
