medium Tenable Cloud Security Plugin ID 460467

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and
 unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI
 library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a
 maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the
 application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

Solution

Update the samba library and its related packages to version 2:4.16.6+dfsg-1 or later.
