Ubuntu 20.04 LTS : Shibboleth vulnerability (USN-4925-1)

medium Nessus Plugin ID 148953

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4925-1 advisory.

 Toni Huttunen and Fraktal Oy discovered that the Shibboleth Service provider allowed content injection due to allowing attacker-controlled parameters in error or other status pages. An attacker could use this to inject malicious content.

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.

Solution

Update the affected packages.
