  1. 31. Nuking Duke Nukem : Reaching the Stack via a Glboal Buffer Overflow in DOS Protected Mode

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Henrik Lindblom; [2023]
    Nyckelord :Computer Security; Operating Systems; Control-flow hijack attacks; Buffer Overflow; Stack; DOS;

    Sammanfattning : Control-flow hijack attacks on software exploit vulnerabilities in the software’s memory handling. Over the years, various security mitigations have been developed to counter these attacks. However, compatibility issues have hindered the adoption of such measures in some legacy systems. LÄS MER

  3. 32. The Efficacy of Forward-Edge Control-Flow Integrity in Mitigating Memory Corruption Vulnerabilities : The Case of the Android Stack

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Viktor Olofsson; [2023]
    Nyckelord :control-flow integrity; CFI; control-flow graph; CFG; memory corruption; Android; vulnerability; android vulnerability; computer security;

    Sammanfattning : Memory corruption is one of the oldest and most prominent problems in the field of computer security. In order to protect the vulnerabilities that arise from memory corruption, a mitigation technique called Control-flow Integrity (CFI) was developed. LÄS MER

  4. 33. Enhancing an Existing Attack Projection System with Deep Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
