EulerOS Virtualization 2.10.0 : openssh (EulerOS-SA-2023-2479)

medium Nessus Plugin ID 179007

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling.
 This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address space. One third-party report states 'remote code execution is theoretically possible.' (CVE-2023-25136)

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.
