|CVSSv2 Base Score:||2.6 (AV:N/AC:H/Au:N/C:N/I:N/A:P)|
|Discovered and Provided:||High-Tech Bridge Security Research Lab|
High-Tech Bridge Security Research Lab discovered an untrusted pointer dereference vulnerability in Corel WordPerfect. Opening of a malicious WPD (WordPerfect Document) causes immediate application crash, resulting in a loss of all unsaved current application data of the user.
The very beginning of the crash occurs within the WPWIN16.DLL module in the STARTAPP function when the application attempts to call the STRNICMP procedure in the MSVCR80 module. Due to a specially crafted WPD file and as a result of the stack modification, it is possible to partially control the destination pointer [EDI] inherited by the STRNICMP function.
As a PoC (Proof of Concept) a file "PoC.wpd" is provided, which causes immediate application crash. Password for archive: k2-0xj)Dhfjhlfs
