CVE-2018-1121

EIP tracks 1 public exploit for CVE-2018-1121. PoCs published by Qualys Corporation.

AI-analyzed exploit summary This is a Qualys Security Advisory detailing multiple vulnerabilities in procps-ng, including CVE-2018-1124, which involves an integer overflow in libprocps's file2strvec() function leading to local privilege escalation. The advisory includes descriptions of vulnerabilities, proof-of-concept code snippets, and technical details.

procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID, thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng up to version 3.3.15, newer versions might be affected also.
