CVE-2016-8387 is a high-severity flaw (CVSS 7.8) affecting argus. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

An exploitable heap-based buffer overflow exists in Iceni Argus. When it attempts to convert a malformed PDF with an object encoded w/ multiple encoding types terminating with an LZW encoded type, an overflow may occur due to a lack of bounds checking by the LZW decoder. This can lead to code execution under the context of the account of the user running it.
