Control flow hijack什么意思

WebThe control flow of a program may be hijacked when the program satisfies several specific conditions. The existing automatic exploit generation technologies for buffer overflow find vulnerability trigger point and generate exploit by checking the control flow state. However, the heap overflow data rarely lead to a control flow hijacking as well as http://web.mit.edu/ha22286/www/papers/MEng15_2.pdf

Web– Hijack the execution flow of a running program – Execute arbitrary code • Requirements – Inject attack code or attack parameters – Abuse vulnerability and modify memory such that control flow is redirected • Change of control flow – alter a code pointer (i.e., value that influences program counter) Webbranch to hijack, to create an entry in the BTB. On the second step, the attacker typically invokes the victim to trigger a code path leading to the targeted indirect branch. When branch prediction on the victim’s indirect branch looks up the BTB, it uses the attacker-injected target. This leads to a speculative control flow hijack. highlands ranch print shop https://delozierfamily.net
