Security Experts:

Hackers Can Target LEADTOOLS Users With Malicious Image Files

Cisco Talos security researchers have discovered multiple vulnerabilities in the LEADTOOLS imaging toolkits that could lead to code execution on the victim system.

Developed by LEAD Technologies Inc., LEADTOOLS represents a collection of toolkits for integrating document, medical, multimedia and imaging technologies into applications tailored for desktop, server, and mobile devices. An SDK and various libraries provide support for multiple operating systems.

According to Talos researchers, multiple vulnerabilities discovered in LEADTOOLS could allow a malicious actor to cause denial-of-service (DoS) conditions and even execute code remotely on an affected system.

The first of these bugs is a heap out-of-bounds write vulnerability in the TIF-parsing functionality of LEADTOOLS 20. Tracked as CVE-2019-5084, the vulnerability can be exploited with the help of a specially crafted TIF image to cause an offset beyond the bounds of a heap allocation to be written.

The CMP-parsing functionality of LEADTOOLS 20, Talos reports, is impacted by an integer underflow security flaw. Tracked as CVE-2019-5099, the issue can be exploited using a specially crafted CMP image file.

Cisco’s researchers also discovered that the BMP header parsing functionality of LEADTOOLS 20 is impacted by an integer overflow bug (tracked as CVE-2019-5100), and that the JPEG2000-parsing functionality of LEADTOOLS 20 has an exploitable heap overflow vulnerability (CVE-2019-5125).

The same as with the first two bugs, an attacker looking to trigger these weaknesses would need specially crafted BMP and J2K image files.

All four vulnerabilities are rated High severity and have a CVSS score of 8.8.

Talos’ security researchers found these bugs in LEADTOOLS 20.0.2019.3.15 in early September and reported them to the vendor on September 10. A patch was released earlier this week.
