CVE-2016-8389
HighSummary
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.
Risk Assessment
Exploitation of this vulnerability could lead to code execution under the context of the account running the application, posing a significant security risk.
Recommendation
It is recommended to update Iceni Argus to the latest version to mitigate this vulnerability and to monitor systems for unauthorized access.
Other vulnerabilities in Iceni Argus
See all- CVE-2016-8388High
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.
- 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 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.
