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. Many Cisco devices such as Cisco RV340, Cisco RV340W, Cisco RV345, Cisco RV345P, Cisco RV260, Cisco RV260P, Cisco RV260W, Cisco 160, and Cisco 160W suffer from having hard-coded credentials, known GNU glibc, known BusyBox, and IoT Inspector identified vulnerabilities. • 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://packetstormsecurity.com/files/154361/Cisco-Device-Hardc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •

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: 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: 0%CPEs: 160EXPL: 0CVE-2015-2808 – SSL/TLS: "Invariance Weakness" vulnerability in RC4 stream cipher
https://notcve.org/view.php?id=CVE-2015-2808
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue. El algoritmo RC4, utilizado en el protocolo TLS y el protocolo SSL, no combina correctamente los datos de estados con los datos de claves durante la fase de inicialización, lo que facilita a atacantes remotos realizar ataques de recuperación de texto claro contra los bytes iniciales de un flujo mediante la captura de trafico de la red que ocasionalmente depende de claves afectadas por la debilidad de la invariabilidad (Invariance Weakness), y posteriormente utilizar un acercamiento de fuerza bruta que involucra valores LSB, también conocido como el problema de 'Bar Mitzvah'. • http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04779034 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10727 http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00022.html • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 5.0EPSS: 3%CPEs: 29EXPL: 1CVE-2013-4458 – glibc: Stack (frame) overflow in getaddrinfo() when called with AF_INET6
https://notcve.org/view.php?id=CVE-2013-4458
Stack-based buffer overflow in the getaddrinfo function in sysdeps/posix/getaddrinfo.c in GNU C Library (aka glibc or libc6) 2.18 and earlier allows remote attackers to cause a denial of service (crash) via a (1) hostname or (2) IP address that triggers a large number of AF_INET6 address results. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-1914. Desbordamiento de búfer basado en pila en la función getaddrinfo en sysdeps/posix/getaddrinfo.c de GNU C Library (también conocido como glibc o libc6) 2.18 y anteriores versiones permite a atacantes remotos provocar una denegación de servicio (caída) a través de (1) un nombre de host o (2) dirección IP que desencadena un gran número de resultados de dirección AF_INET6. NOTA: esta vulnerabilidad existe por un parche incompleto para CVE-2013-1914. It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. • http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00036.html http://www.mandriva.com/security/advisories?name=MDVSA-2013:283 http://www.mandriva.com/security/advisories?name=MDVSA-2013:284 https://security.gentoo.org/glsa/201503-04 https://sourceware.org/bugzilla/show_bug.cgi?id=16072 https://sourceware.org/ml/libc-alpha/2013-10/msg00733.html https://access.redhat.com/security/cve/CVE-2013-4458 https://bugzilla.redhat.com/show_bug.cgi?id=1022280 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
