Ubuntu Security Notice USN-2780-2

Ubuntu Security Notice 2780-2 – USN-2780-1 fixed a vulnerability in the MiniUPnP library in Ubuntu 12.04 LTS, Ubuntu 14.04 LTS, and Ubuntu 15.04. This update provides the corresponding update for Ubuntu 15.10. Aleksandar Nikolic discovered a buffer overflow vulnerability in the XML parser functionality of the MiniUPnP library. A remote attacker could use this to cause a denial of service (application crash) or possibly execute arbitrary code with privileges of the user running an application that uses the MiniUPnP library. Various other issues were also addressed.

Realtyna RPL 8.9.2 CSRF / Cross Site Scripting

The Realtyna RPL application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. Multiple cross site scripting vulnerabilities were also discovered. The issue is triggered when input passed via the multiple parameters is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site.
