EulerOS 2.0 SP5 : samba (EulerOS-SA-2022-1551)

high Nessus Plugin ID 160108

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 :

 - 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)

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.
