An update for samba is now available for openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1817 Final 1.0 1.0 2022-08-11 Initial 2022-08-11 2022-08-11 openEuler SA Tool V1.0 2022-08-11 samba security update An update for samba is now available for openEuler-20.03-LTS-SP3. Samba is a suite of programs for Linux and Unix to interoperate with Windows. Security Fix(es): 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) An update for samba is now available for openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of High.
