stack-overflow-and-rop

To build a ROP chain for a buffer overflow, you overwrite the return address with gadget addresses to hijack control flow. This Skill provides detailed steps for constructing ROP chains in Linux userland binaries using pwntools, ropper, and ROPgadget.

ret2libc is a stack overflow exploitation technique used when NX is enabled, redirecting execution to libc functions instead of injected shellcode. You need it when the binary's stack is non-executable, preventing direct shellcode execution.

Yes, you can use pwntools and ROPgadget together to analyze Linux binaries and construct ROP chains. This Skill requires these dependencies to identify gadgets, understand binary protection mechanisms, and automate the exploitation workflow.

ret2dlresolve works by crafting fake relocation structures to trick the dynamic linker into resolving arbitrary functions without a libc leak. This Skill guides you through constructing the required payloads to exploit the dynamic linking process.

SROP, or Sigreturn-Oriented Programming, utilizes a fake Signal Frame to set all registers at once via the sigreturn system call. This technique allows precise control over the CPU state when standard ROP gadgets are insufficient.

ret2csu limitations include relying on specific functions like __libc_csu_init to populate registers, which may not exist in fully RELRO binaries. This Skill covers ret2csu but emphasizes understanding binary protection mechanisms to determine applicability.
