Package        : samba
CVE ID         : CVE-2022-2031 CVE-2022-32742 CVE-2022-32744 CVE-2022-32745
                 CVE-2022-32746
Debian Bug     : 1016449

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,
print, and login server for Unix.

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.
