CVE-2019-5596

This exploit leverages a use-after-free vulnerability in FreeBSD's file descriptor handling to achieve local privilege escalation. It manipulates file descriptors and dirty buffers to corrupt kernel memory, ultimately allowing an attacker to overwrite critical files like /etc/libmap.conf.

This exploit targets a use-after-free vulnerability in FreeBSD's file descriptor handling (CVE-2019-5596). It manipulates file descriptors and leverages race conditions to achieve local privilege escalation by corrupting kernel memory structures.

This is a privilege escalation exploit for FreeBSD (CVE-2019-5596) leveraging a use-after-free vulnerability in the file descriptor handling mechanism. The exploit uses a combination of multithreading, file operations, and socket manipulation to trigger the vulnerability and achieve root access.
