CWE-122: Heap-based Buffer Overflow Decription Describe the Bug A heap-buffer-overflow vulnerability has been identified in theOpenDDLParser::parseStructurefunction within the Assimp library, specifically during the processing of OpenGEX files. The issue arises when reading beyond the bounds of a memo...
Consequently, if we execute “sudoedit -s”, then we set both MODE_EDIT and MODE_SHELL (but not MODE_RUN), we avoid the escape code, reach the vulnerable code, and overflow the heap-based buffer “user_args” through a command-line argument that ends with a ...

CVE-2023-27997 is a heap-based buffer overflow vulnerability in the secure socket layer virtual private network (SSL VPN) functionality in FortiOS and FortiProxy in Fortinet devices including its FortiGate Next Generation Firewalls (NGFW). An unauthenticated, remote attacker could ...
Isolating the root cause of a heap-based buffer overflow can be tricky at best. Thankfully, Microsoft provides a great tool called the Application verifier, which makes the process significantly gentler. In this post, we will look at how to use the Application Verifier to pinpo...
