Trust Security disclosed a widespread DOS vulnerability affecting 100+ DeFi projects that misuse EIP-2612's permit() function in contract call compositions. When permit() is frontrun as part of a multi-step transaction, it causes the entire function to revert, enabling denial-of-service attacks—a flaw in the original EIP's threat model that assumes A;A* (reverted action) is harmless, but fails when A is part of a sequence A;B;C.

Educational article explaining how buffer overflow vulnerabilities occur in low-level languages like C, how attackers exploit them via stack frame manipulation and return address overwriting, and what defense mechanisms (DEP, ASLR, stack canaries) are used to mitigate them.
