Ubuntu Security Notice 5841-1 - It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges. This issue was only fixed in Ubuntu 14.04 ESM. It was discovered that LibTIFF was incorrectly accessing a data structure when processing data with the tiffcrop tool, which could lead to a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

Some Hikvision Hybrid SAN products were vulnerable to multiple remote code execution (command injection) vulnerabilities, including reflected cross site scripting, Ruby code injection, classic and blind SQL injection resulting in remote code execution that allows an adversary to execute arbitrary operating system commands and more. However, an adversary must be on the same network to leverage this vulnerability to execute arbitrary commands.

Secure Web Gateway version 10.2.11 suffers from a cross site scripting vulnerability. RedTeam Pentesting identified a vulnerability which allows attackers to craft URLs to any third-party website that result in arbitrary content to be injected into the response when accessed through the Secure Web Gateway. While it is possible to inject arbitrary content types, the primary risk arises from JavaScript code allowing for cross site scripting.
