<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Samba is a suite of programs for Linux and Unix to interoperate with Windows.
Security Fix(es):
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)
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)
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 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)
As per samba upstream advisory:All versions of Samba prior to 4.16.x built with Heimdal Kerberos are vulnerable to an Elevation of Privilege attack. If the password of a user expires and need to be changed, a user could get a krbtgt using kpasswd with canonicalization turned on. The KDC should only provide a ticket for kadmin/changepw but returns a krbtgt. So a user could skip the password change and just use the krbtgt to get service tickets and use services in the forest.(CVE-2022-2031)</Note>
<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for samba is now available for openEuler-22.03-LTS.
openEuler Security has rated this update as having a security impact of High. 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>

<Notes>
<Note Title="Vulnerability Description" Type="General" Ordinal="5" xml:lang="en">As per samba upstream advisory:All versions of Samba prior to 4.16.x built with Heimdal Kerberos are vulnerable to an Elevation of Privilege attack. If the password of a user expires and need to be changed, a user could get a krbtgt using kpasswd with canonicalization turned on. The KDC should only provide a ticket for kadmin/changepw but returns a krbtgt. So a user could skip the password change and just use the krbtgt to get service tickets and use services in the forest.</Note>
