## Overview

A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by causing the system to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations.

## Affected

- `libssh <= 0.11.3`
- `enterprise_linux = 9.0`
- `enterprise_linux = 10.0`
