In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2, the user's password is kept in a session-child process spawned from the LightDM daemon. This can expose the credential in cleartext.

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

  - In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2, the user's password is kept in a session-child     process spawned from the LightDM daemon. This can expose the credential in cleartext. (CVE-2018-20781)

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

According to the version of the gnome-keyring packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2,     the user's password is kept in a session-child process     spawned from the LightDM daemon. This can expose the     credential in cleartext.(CVE-2018-20781)

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 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3894-1 advisory.

    It was discovered that GNOME Keyring incorrectly cleared out credentials supplied to the PAM module. A     local attacker could possibly use this issue to discover login credentials.

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.
