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 •
CVSS: 9.8EPSS: 3%CPEs: 24EXPL: 0CVE-2015-8778 – glibc: Integer overflow in hcreate and hcreate_r
https://notcve.org/view.php?id=CVE-2015-8778
Integer overflow 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 execute arbitrary code via the size argument to the __hcreate_r function, which triggers out-of-bounds heap-memory access. Desbordamiento de entero 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 ejecutar código arbitrario a través del argumento size a la función the __hcreate_r, lo que desencandena el acceso fuera de rango a memoria dinámica. An integer overflow vulnerability was found in hcreate() and hcreate_r() functions which could result in an out-of-bounds memory access. This could lead to application crash or, potentially, arbitrary code execution.

https://notcve.org/view.php?id=CVE-2015-8779
Stack-based buffer overflow in the catopen 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 execute arbitrary code via a long catalog name. Desbordamiento de buffer basado en pila en la función catopen en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permite a atacantes dependientes de contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de un nombre de catálogo largo. A stack based buffer overflow vulnerability was found in the catopen() function. An excessively long string passed to the function could cause it to crash or, potentially, execute arbitrary code.

CVSS: 6.8EPSS: 8%CPEs: 12EXPL: 0CVE-2015-1781 – glibc: buffer overflow in gethostbyname_r() and related functions with misaligned buffer
https://notcve.org/view.php?id=CVE-2015-1781
Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer. Desbordamiento de buffer en gethostbyname_r y otras funciones NSS no especificadas en la librería C de GNU (también conocida como glibc o libc6) en versiones anteriores a 2.22, permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o ejecutar código arbitrario a través de una respuesta DNS manipulada, lo que desencadena una llamada con un buffer incorrectamente alineado. A buffer overflow flaw was found in the way glibc's gethostbyname_r() and other related functions computed the size of a buffer when passed a misaligned buffer as input. An attacker able to make an application call any of these functions with a misaligned buffer could use this flaw to crash the application or, potentially, execute arbitrary code with the permissions of the user running the application. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177404.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://www.debian.org/security/2016/dsa-3480 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/74255 http://www.securitytracker.com/id/1032178 http://www.ubuntu.com/usn/USN-2985-1 http://www.ubu • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.0EPSS: 1%CPEs: 9EXPL: 2CVE-2014-8121 – glibc: Unexpected closing of nss_files databases after lookups causes denial of service
https://notcve.org/view.php?id=CVE-2014-8121
DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) 2.21 and earlier does not properly check if a file is open, which allows remote attackers to cause a denial of service (infinite loop) by performing a look-up on a database while iterating over it, which triggers the file pointer to be reset. DB_LOOKUP en nss_files/files-XXX.c en Name Service Switch (NSS) en GNU C Library (también conocida como glibc o libc6) 2.21 y versiones anteriores no comprueba correctamente si un archivo está abierto, lo que permite a atacantes remotos causar una denegación de servicio (bucle infinito) realizando una búsqueda en una base de datos mientras itera sobre ella, lo que desencadena que el puntero al archivo sea reestablecido. It was found that the files back end of Name Service Switch (NSS) did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://rhn.redhat.com/errata/RHSA-2015-0327.html http://www.debian.org/security/2016/dsa-3480 http://www.securityfocus.com/bid/73038 http://www.ubuntu.com/usn/USN-2985-1 http://www.ubuntu.com/usn/USN-2985-2 https://bugzilla.redhat.com/show_bug.cgi?id=1165192 https://security.gentoo.org/glsa/201602-02 https://sourcewa • CWE-17: DEPRECATED: Code CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
