EulerOS 2.0 SP11 : openssh (EulerOS-SA-2023-2863)

critical Nessus Plugin ID 188268

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an incomplete fix for CVE-2016-10009. (CVE-2023-38408)

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 openssh packages.
