Loading vulnerability…
Mutagen Astronomy is an integer-overflow vulnerability in the Linux kernel ELF execution path, specifically create_elf_tables() during execve() processing. On affected 64-bit kernels, attacker-controlled argument and environment counts can cause the calculation of the number of ELF stack-table items to overflow to a negative value. Subsequent stack-pointer rounding and placement calculations can increase rather than decrease the user stack pointer, redirecting it into attacker-controlled argument or environment-string memory. This corrupted layout can allow unsafe dynamic-loader environment variables to survive sanitization when a privileged executable is launched.

This repository contains a proof-of-concept (POC) exploit for CVE-2018-14634, a local privilege escalation vulnerability in the Linux kernel affecting versions 2.6.x, 3.10.x, and 4.14.x. The repository consists of a README.md describing the vulnerability and a single C source file (poc-exploit.c) implementing the exploit. The exploit works by crafting a large number of arguments and environment variables, manipulating memory layout, and executing a SUID binary (expected to be present as ./poc-suidbin) to trigger a buffer overflow in the kernel. The code uses temporary files in /tmp for argument vector manipulation. The exploit must be run locally by an attacker with access to the system, and if successful, results in privilege escalation. No network endpoints are involved; the attack vector is purely local. The code is a POC and does not include a weaponized or customizable payload.
