CVE-2017-17557: Foxitsoftware Foxit Reader

High severity, CVSS 8.8. EPSS: 3.5% chance of exploitation in the next 30 days.

In Foxit Reader before 9.1 and Foxit PhantomPDF before 9.1, a flaw exists within the parsing of the BITMAPINFOHEADER record in BMP files. The issue results from the lack of proper validation of the biSize member, which can result in a heap based buffer overflow. An attacker can leverage this to execute code in the context of the current process.

Affected products

• Foxitsoftware Foxit Reader: before 9.1 (fixed in 9.1)
• Foxitsoftware Phantompdf: before 9.1 (fixed in 9.1)
