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
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 privileged execve() calls. This issue affects kernel versions before 4.8. Una condición de carrera en la función perf_event_open() permite a los atacantes locales filtrar datos confidenciales desde los programas setuid. Como no se mantienen bloqueos relevantes (en particular, la función cred_guard_mutex) durante la llamada ptrace_may_access(), es posible que la tarea de destino especificada realice un syscall execve() con la ejecución setuid anterior a que perf_event_alloc() realmente se conecte, permitiendo que un atacante omita la comprobación ptrace_may_access() y la llamada perf_event_exit_task(current) que se realiza en install_exec_creds() durante las llamadas privilegiadas execve(). • http://www.securityfocus.com/bid/89937 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3901 https://lists.debian.org/debian-lts-announce/2019/05/msg00041.html https://lists.debian.org/debian-lts-announce/2019/05/msg00042.html https://security.netapp.com/advisory/ntap-20190517-0005 https://access.redhat.com/security/cve/CVE-2019-3901 https://bugzilla.redhat.com/show_bug.cgi?id=1701245 • CWE-667: Improper Locking •

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Windows DLL). Supported versions that are affected are Java SE: 7u181 and 8u172. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.securityfocus.com/bid/104781 http://www.securitytracker.com/id/1041302 https://security.netapp.com/advisory/ntap-20180726-0001 •
