CVE-2022-2031

Luke Howard reported that Samba AD users can bypass certain restrictions associated with changing passwords. A user who has been requested to change their password can exploit this to obtain and use tickets to other services.

CVE-2022-32742

Luca Moro reported that a SMB1 client with write access to a share can cause server memory content to be leaked.

CVE-2022-32744

Joseph Sutton reported that Samba AD users can forge password change requests for any user, resulting in privilege escalation.

CVE-2022-32745

Joseph Sutton reported that Samba AD users can crash the server process with a specially crafted LDAP add or modify request.

CVE-2022-32746

Joseph Sutton and Andrew Bartlett reported that Samba AD users can cause a use-after-free in the server process with a specially crafted LDAP add or modify request.

For the stable distribution (bullseye), these problems have been fixed in version 2:4.13.13+dfsg-1~deb11u5. The fix for CVE-2022-32745 required an update to ldb 2:2.2.3-2~deb11u2 to correct the defect.

We recommend that you upgrade your samba packages.

For the detailed security status of samba please refer to its security tracker page at: [link moved to references]");
