Slackware Linux 15.0 / current samba Vulnerability (SSA:2022-298-02)

medium Nessus Plugin ID 166493

Language:

Synopsis

The remote Slackware Linux host is missing a security update to samba.

Description

The version of samba installed on the remote host is prior to 4.15.11 / 4.17.2. It is, therefore, affected by a vulnerability as referenced in the SSA:2022-298-02 advisory.

 - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the affected samba package.
