Debian DSA-5205-1 : samba - security update

high Nessus Plugin ID 164092

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5205 advisory.

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. For the detailed security status of samba please refer to its security tracker page at: https://security-tracker.debian.org/tracker/samba
