7.8

CVSS v3.1

Official Description

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.

Technical Analysis

CVE-2016-8387 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
