Iceni Argus loadTrailer function to deal with special PDF files there is a heap destruction vulnerability, attackers can exploit the vulnerability to build malicious PDF files, inducing users to parse, can make t...

Iceni Argus Integer Overflow Vulnerability

Iceni Argus is the British Iceni company's set of PDF document type conversion tool. Iceni Argus handles special PDF files with an integer overflow vulnerability that can be exploited by an attacker to build malicious PDF files and trick users into parsing them, which can crash the application...

CVE-2016-8389

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...

CVE-2016-8715

An exploitable heap corruption vulnerability exists in the loadTrailer functionality of Iceni Argus version 6.6.05. A specially crafted PDF file can cause a heap corruption resulting in arbitrary code execution. An attacker can send/provide a malicious PDF file to trigger this vulnerability...

CVE-2016-8388

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...

CVE-2016-8388

Iceni Argus contains a heap-overwrite vulnerability in its PDF-to-XML conversion path. Specifically, during glyph-map handling, an index trusted from a font object can be used to write a font name pointer into an out-of-bounds location, enabling memory corruption and potential code execution. Rep...

CVE-2016-8715

Iceni Argus CVE-2016-8715 affects Argus 6.6.05. The root cause is a heap corruption in loadTrailer where the PDF Size field from the trailer is used to allocate memory (icnChainAlloc) and then memset-ing 24*v166 bytes. If Size is negative (e.g., -1 or large unsigned interpretations), icnChainAllo...
