Linux Heap Fast Bin Poisoning part 1

In this paper, I introduce the reader to a heap metadata corruption against the current Linux Heap allocator, ptmalloc. The attack is performed via corrupting, or poisoning the fast bin such that malloc returns a near arbitrary pointer. This may allow for control flow hijacking if malloc returns a pointer to a function pointer and an attacker is able to write to that malloc returned buffer.

  1. Engineers who wish to migrate to Australia must submit a Competency Demonstration Report and the Engineers Australia must approve it. Thus, engineering students look forward to getting Cdr Australia which assists them to get a flawless CDR. This reduces the chances of rejection by the EA.
    Most students and experienced civil engineers are today looking forward to migrating to Australia as the job scope is better and bigger with a high pay scale. Therefore, getting CDR help is the only scope to gain entry into the country.
    The CDR for Engineers Australia must be impressive and abide by the ANZSCO code and guidelines. It should also showcase the skills of the applicants as a suitable civil engineer to work according to the Australian rules and regulations.
    The service providers who assist the students with CDR have experienced CDR report writers. These writers know the requirements of a CDR and do it accordingly.
