A Novel Advanced Heap Corruption and Security Method

TL;DR

This paper introduces a new heap security method focusing on Solaris OS's dynamic memory management, utilizing splay tree structures to enhance protection against heap overflows and attacks.

Contribution

It proposes a novel security approach at the OS level, specifically targeting Solaris's SysVmalloc and splay tree-based memory allocation.

Findings

Enhanced heap security at the OS level

Use of splay trees for secure memory management

Addressed specific vulnerabilities in Solaris's heap system

Abstract

Heap security has been a major concern since the past two decades. Recently many methods have been proposed to secure heap i.e. to avoid heap overrun and attacks. The paper describes a method suggested to secure heap at the operating system level. Major emphasis is given to Solaris operating system's dynamic memory manager. When memory is required dynamically during runtime, the SysVmalloc acts as a memory allocator.Vmalloc allocates the chunks of memory in the form of splay tree structure. A self adjusting binary tree structure is reviewed in the paper, moreover major security issue to secure heap area is also suggested in the paper
