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') •
CVSS: 4.6EPSS: 0%CPEs: 8EXPL: 0CVE-2014-7817 – glibc: command execution in wordexp() with WRDE_NOCMD specified
https://notcve.org/view.php?id=CVE-2014-7817
The wordexp function in GNU C Library (aka glibc) 2.21 does not enforce the WRDE_NOCMD flag, which allows context-dependent attackers to execute arbitrary commands, as demonstrated by input containing "$((`...`))". La función wordexp en GNU C Library (también conocido como glibc) 2.21 no fuerza el indicador WRDE_NOCMD, lo que permite a atacantes dependientes de contexto ejecutar comandos arbitrarios, tal y como fue demostrado por entradas que contienen '$((`...`))'. It was found that the wordexp() function would perform command substitution even when the WRDE_NOCMD flag was specified. An attacker able to provide specially crafted input to an application using the wordexp() function, and not sanitizing the input correctly, could potentially use this flaw to execute arbitrary commands with the credentials of the user running that application. • http://linux.oracle.com/errata/ELSA-2015-0016.html http://linux.oracle.com/errata/ELSA-2015-0092.html http://lists.opensuse.org/opensuse-updates/2015-02/msg00089.html http://rhn.redhat.com/errata/RHSA-2014-2023.html http://seclists.org/oss-sec/2014/q4/730 http://secunia.com/advisories/62100 http://secunia.com/advisories/62146 http://www.debian.org/security/2015/dsa-3142 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.oracle.com&#x • CWE-20: Improper Input Validation CWE-440: Expected Behavior Violation •

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 •
