Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4669-1 advisory.

 - XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2. Due to improper handling of RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be bypassed. Malicious script content from HTML e-mail can be executed within the application context via crafted use of (for example) a NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA element. (CVE-2019-12970)

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