Foxit Reader contains multiple vulnerabilities that may allow an attacker to execute arbitrary code.
Foxit Reader is software designed to view Portable Document Format (PDF) files. Foxit Reader contains multiple vulnerabilities in the handling of JPX (JPEG2000) streams. These vulnerabilities may result in memory corruption.
Note: Foxit Reader does not contain the ability to decode JPEG2000 data by default. The JPEG2000 / JBIG Decoder add-on must be installed for Foxit Reader to be vulnerable. When Foxit Reader encounters a PDF document that has JPEG2000 or JBIG data, the user will automatically be prompted to install the add-on, however.
By convincing a user to open a malicious PDF file, an attacker may be able to execute code or cause a vulnerable PDF viewer to crash. The PDF could be emailed as an attachment or hosted on a website.
