Iceni Argus and Infix contain a stack buffer overflow in the handling of flate-compressed PDF content, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Iceni Argus is a PDF conversion library. Argus 6.20 and earlier fail to properly handle malformed flate-compressed content in PDF documents, resulting in a stack buffer overflow. Other Argus applications that share the same codebase with Argus may also be affected. We have confirmed that Iceni Infix 5.04 is affected by this vulnerability.
By causing the Iceni PDF library to parse a specially-crafted PDF document, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the application using the library.
We are currently unaware of a practical solution to this problem. Please consider the following workarounds.
