Fuzzing µCOS protocol stacks, Part 2: Handling multiple requests per test case

So far in this series, Ive developed a fuzzer for the µC/HTTP-server. As described in the previous post, this fuzzer reads from a file to enable compatibility with AFL++. That implementation only fuzzes a single request at a time. Although that single request fuzzer uncovered a few security...

Fuzzing µC/OS protocol stacks, Part 3: TCP/IP server fuzzing, implementing a TAP driver

This is the final post in the three-part series that details techniques I used to fuzz two µC/OS protocol stacks: µC/TCP-IP and µC/HTTP-server. The first post highlighted code modifications necessary for developing a fuzzing harness tailored for the µC/HTTP-server. The second discussed a techniqu...

Multiple vulnerabilities in Adobe Acrobat Reader could lead to remote code execution

Cisco Talos has disclosed more than 30 vulnerabilities in February, including seven in Adobe Acrobat Reader, one of the most popular PDF editing and reading software currently available. Adversaries could exploit these vulnerabilities to trigger the reuse of a previously freed object, thus causin...
