EulerOS Virtualization 2.9.1 : protobuf (EulerOS-SA-2022-2188)

medium Nessus Plugin ID 163601

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message.
 Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater. (CVE-2021-22570)

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 protobuf packages.
