CentOS 9 : openssh-8.7p1-34.el9

critical Nessus Plugin ID 191292

Language:

Synopsis

The remote CentOS host is missing a security update for openssh.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the openssh-8.7p1-34.el9 build changelog.

 - 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the CentOS 9 Stream openssh package.
