Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2018-6323. PoCs published by r4xis.

AI-analyzed exploit summary This exploit demonstrates an integer overflow vulnerability in objdump (CVE-2018-6323) by crafting a malicious ELF file with manipulated program header counts, leading to a crash. It compiles a simple C program, modifies the ELF headers to trigger the overflow, and executes objdump to exploit the flaw.

Description

The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
