What is CVE-2024-54661?

The readline.sh script in Socat versions up to 1.8.0.1 contains a vulnerability related to its reliance on a temporary file located at /tmp/$USER/stderr2. This design choice creates a potential security risk, as it could allow unauthorized users to interact with or manipulate sensitive data stored in this temporary location. As a result, the script's implementation raises significant concerns about file permissions and the possibility of unauthorized data access, highlighting a need for improved handling of temporary files in future releases.
