Detailsinfo

A vulnerability has been found in Iceni Argus (the affected version is unknown) and classified as critical. Affected by this vulnerability is an unknown code of the component PDF Converter. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An exploitable integer-overflow vulnerability exists within Iceni Argus. When it attempts to convert a malformed PDF to XML, it will attempt to convert each character from a font into a polygon and then attempt to rasterize these shapes. As the application attempts to iterate through the rows and initializing the polygon shape in the buffer, it will write outside of the bounds of said buffer. This can lead to code execution under the context of the account running it.

The bug was discovered 02/27/2017. The weakness was shared 02/28/2017 by Cisco with Cisco Talos (Website). It is possible to read the advisory at securityfocus.com.
