CVE-2016-8386
HighSummary
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.
Risk Assessment
This vulnerability can lead to code execution under the context of the user running the tool, posing a serious security risk to the system.
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-2016-8389High
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-2016-8388High
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-2016-8385High
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 heap-based buffer overflow exists in Iceni Argus. When it attempts to convert a PDF containing a malformed font to XML, the tool will attempt to use a size out of the font to search through a linked list of buffers to return. Due to a signedness issue, a buffer smaller than the requested size will be returned. Later when the tool tries to populate this buffer, the overflow will occur which can lead to code execution under the context of the user running the tool.
