CVSS: 9.1EPSS: 0%CPEs: 24EXPL: 0CVE-2015-8776 – glibc: Segmentation fault caused by passing out-of-range data to strftime()
https://notcve.org/view.php?id=CVE-2015-8776
The strftime function in the GNU C Library (aka glibc or libc6) before 2.23 allows context-dependent attackers to cause a denial of service (application crash) or possibly obtain sensitive information via an out-of-range time value. La función strftime en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permite a atacantes dependientes del contexto causar una denegación de servicio (caída de aplicación) o posiblemente obtener información sensible a través de un valor de tiempo fuera de rango. It was found that out-of-range time values passed to the strftime() function could result in an out-of-bounds memory access. This could lead to application crash or, potentially, information disclosure. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184626.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00042.html http://rhn.redhat.com/errata/RHSA-2017-0680.html http&# • CWE-189: Numeric Errors •
CVSS: 7.0EPSS: 0%CPEs: 1EXPL: 1CVE-2015-8777 – glibc: LD_POINTER_GUARD in the environment is not sanitized
https://notcve.org/view.php?id=CVE-2015-8777
The process_envvars function in elf/rtld.c in the GNU C Library (aka glibc or libc6) before 2.23 allows local users to bypass a pointer-guarding protection mechanism via a zero value of the LD_POINTER_GUARD environment variable. La función process_envvars en elf/rtld.c en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permite a usuarios locales eludir un mecanismo de protección de puntero a través de un valor cero de la variable de entorno LD_POINTER_GUARD. It was found that the dynamic loader did not sanitize the LD_POINTER_GUARD environment variable. An attacker could use this flaw to bypass the pointer guarding protection on set-user-ID or set-group-ID programs to execute arbitrary code with the permissions of the user running the application. • http://hmarco.org/bugs/glibc_ptr_mangle_weakness.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177404.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00039.html http://www.debian.org/security/2016/dsa-3480 http://www.openwall& • CWE-254: 7PK - Security Features •

https://notcve.org/view.php?id=CVE-2010-3192
Certain run-time memory protection mechanisms in the GNU C Library (aka glibc or libc6) print argv[0] and backtrace information, which might allow context-dependent attackers to obtain sensitive information from process memory by executing an incorrect program, as demonstrated by a setuid program that contains a stack-based buffer overflow error, related to the __fortify_fail function in debug/fortify_fail.c, and the __stack_chk_fail (aka stack protection) and __chk_fail (aka FORTIFY_SOURCE) implementations. Algunos mecanismos run-time de protección de memoria en la Librería C de GNU (también conocido como glibc o libc6) print argv[0] y backtrace information, lo cual permite a atacantes dependientes del contexto obtener información sensible de procesos de memoria mediante la ejecución de un programa incorrecto, como el demostrado por un programa setuid que contiene un error de desbordamiento de búfer basado en pila, relacionado con la función __fortify_fail en debug/fortify_fail.c, y las implementaciones __stack_chk_fail (también conocida como stack protection) y __chk_fail (también conocida como FORTIFY_SOURCE). • http://seclists.org/fulldisclosure/2010/Apr/399 http://www.openwall.com/lists/oss-security/2010/08/25/8 http://www.openwall.com/lists/oss-security/2010/08/31/6 http://www.openwall.com/lists/oss-security/2010/08/31/7 http://www.openwall.com/lists/oss-security/2010/09/02/2 http://www.openwall.com/lists/oss-security/2010/09/02/3 http://www.openwall.com/lists/oss-security/2010/09/02/4 http://www.openwall.com/lists/oss-security/2010/09/02/5 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
