FreeBSD rtld execl() Privilege Escalation Exploit

This Metasploit module exploits a vulnerability in the FreeBSD run-time link-editor rtld. The rtld unsetenv function fails to remove LD environment variables if findenv fails. This can be abused to load arbitrary shared objects using LDPRELOAD, resulting in privileged code execution. This module...

CVE-2019-3901

CVE-2019-3901 describes a race condition in perf_event_open() that can leak data from setuid processes. The root cause is that cred_guard_mutex is not held during the ptrace_may_access() check, allowing a target task to execve() with setuid execution before perf_event_alloc() attaches, bypassing ...
