EulerOS Virtualization 2.10.1 : samba (EulerOS-SA-2022-2066)

high Nessus Plugin ID 163214

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed. (CVE-2021-43566)

 - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide '...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver.' Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

 - Potential security vulnerabilities have been identified in HPE SimpliVity Omnistack for Hyper-V. The vulnerabilities could be remotely exploited to allow code execution, information leak and impersonate arbitrary services. (CVE-2022-0336)

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.
