## Overview

A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system.

## Affected

- `automatic_bug_reporting_tool`
- `fedora = 43`
- `fedora = 44`
- `enterprise_linux = 7.0`
- `enterprise_linux = 8.0`
