socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a denial of service or disruption of the target process.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

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

  - socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as     Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a     denial of service or disruption of the target process. (CVE-2023-24626)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as     Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a     denial of service or disruption of the target process. (CVE-2023-24626)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has a package installed that is affected by a vulnerability as referenced in the USN-6198-1 advisory.

    It was discovered that GNU Screen was not properly checking user identifiers before sending certain     signals to target processes. If GNU Screen was installed as setuid or setgid, a local attacker could     possibly use this issue to cause a denial of service on a target application.

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

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

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-224 advisory.

  - socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as     Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a     denial of service or disruption of the target process. (CVE-2023-24626)

Note that Nessus has not tested for this issue 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 4.1.0-0.27.20120314git3c2946. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2023 advisory.

  - socket.c in GNU Screen through 4.9.0, when installed setuid or setgid (the default on platforms such as     Arch Linux and FreeBSD), allows local users to send a privileged SIGHUP signal to any PID, causing a     denial of service or disruption of the target process. (CVE-2023-24626)
