CVE-2016-8388
HighSummary
An exploitable arbitrary heap-overwrite vulnerability exists within Iceni Argus. The issue arises when converting a malformed PDF to XML, as the software trusts an index within the font object and uses it to write the font's name to an object within an array.
Risk Assessment
Exploitation of this vulnerability could lead to unauthorized memory access, potentially resulting in the execution of malicious code or application instability. Organizations should be aware of the risks associated with processing unknown PDF files.
Recommendation
It is recommended to update Iceni Argus to the latest version to mitigate this vulnerability. Additionally, implementing security controls when processing PDF files can help minimize risk.

See all- CVE-2016-8389High
An exploitable integer-overflow vulnerability exists within Iceni Argus when converting a malformed PDF to XML. The application attempts to convert each character from a font into a polygon, leading to writing outside the bounds of the buffer.
- CVE-2016-8387High
There is a heap-based buffer overflow vulnerability in Iceni Argus that can be exploited. The issue occurs when converting a malformed PDF, leading to a lack of bounds checking by the LZW decoder.
- CVE-2016-8386High
There is a heap-based buffer overflow vulnerability in Iceni Argus that can be exploited. The issue occurs when converting a PDF with a malformed font to XML, leading to a buffer smaller than the requested size being returned.
- CVE-2016-8385High
An exploitable uninitialized variable vulnerability leading to a stack-based buffer overflow exists in Iceni Argus. The issue occurs when converting a malformed PDF to XML, allowing an attacker to write outside the bounds of a stack buffer.
Original NVD description (English source)
An exploitable arbitrary heap-overwrite vulnerability exists within Iceni Argus. When it attempts to convert a malformed PDF to XML, it will explicitly trust an index within the specific font object and use it to write the font's name to a single object within an array of objects.
