CVSS: 5.6EPSS: 0%CPEs: 11EXPL: 0CVE-2019-3901 – kernel: perf_event_open() and execve() race in setuid programs allows a data leak
https://notcve.org/view.php?id=CVE-2019-3901
22 Apr 2019 — A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs. As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it is possible for the specified target task to perform an execve() syscall with setuid execution before perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check and the perf_event_exit_task(current) call that is performed in install_exec_creds() during ... • http://www.securityfocus.com/bid/89937 • CWE-667: Improper Locking •

11 Apr 2019 — The Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is enabled and ia32_aout is loaded, allows local users to bypass ASLR on setuid a.out programs (if any exist) because install_exec_creds() is called too late in load_aout_binary() in fs/binfmt_aout.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat.

11 Apr 2019 — The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the ptrace_may_access() check has a race condition when reading /proc/pid/stat. El kernel de Linux anterior a la versión 4.8 permite a los usuarios locales eludir ASLR en programas setuid (como /bin/su) porque install_exec_creds() es llamado demasiado tarde en load_elf_binary() en fs/binfmt_elf.c, y por lo tanto l... • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html • CWE-250: Execution with Unnecessary Privileges CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
