A minor information leak when running Screen with setuid-root privileges allows unprivileged users to deduce information about a path that would otherwise not be available. Affected are older Screen versions, as well as version 5.0.0.

According to the versions of the screen package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    For a short time they PTY is set to mode 666, allowing any user on the system to connect to the screen     session.(CVE-2025-46802)

    A minor information leak when running Screen with setuid-root privileges allows unprivileged users to     deduce information about a path that would otherwise not be available.(CVE-2025-46804)

    Screen version 5.0.0 and older version 4 releases have  a TOCTOU race potentially allowing to send SIGHUP,     SIGCONT to privileged processes when installed setuid-root.(CVE-2025-46805)

Tenable has extracted the preceding description block directly from the EulerOS screen security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A minor information leak when running Screen with setuid-root privileges allows unprivileged users to     deduce information about a path that would otherwise not be available. Affected are older Screen versions,     as well as version 5.0.0. (CVE-2025-46804)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 4abd86c1-366d-11f0-9c0c-000c29ffbb6c advisory.

    The screen project reports:
    Multiple security issues in screen.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of screen installed on the remote host is prior to 4.9.1 / 5.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2025-133-01 advisory.

    New screen packages are available for Slackware 15.0 and -current to fix security issues.
