Synopsis

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4860-1 advisory.

 Zack Flack discovered that Monit incorrectly handled certain input. A remote authenticated user could exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2019-11454)

 Zack Flack discovered a buffer overread when Monit decoded certain crafted URLs. An attacker could exploit this to potentially leak sensitive information. (CVE-2019-11455)
