EulerOS 2.0 SP11 : samba (EulerOS-SA-2023-1021)

medium Nessus Plugin ID 169578

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected samba packages.
