EulerOS Virtualization 3.0.2.2 : cifs-utils (EulerOS-SA-2023-1247)

high Nessus Plugin ID 170786

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the cifs-utils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in cifs-utils in versions before 6.13. A user when mounting a krb5 CIFS file system from within a container can use Kerberos credentials of the host. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2021-20208)

 - In cifs-utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs ip= command-line argument could lead to local attackers gaining root privileges. (CVE-2022-27239)

 - cifs-utils through 6.14, with verbose logging, can cause an information leak when a file contains = (equal sign) characters but is not a valid credentials file. (CVE-2022-29869)

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 cifs-utils packages.
