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-8.7p1-42.el9 build changelog.

 - A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead to sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. (CVE-2024-6387)

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.
