CVE-2016-2324 – git: path_name() integer truncation and overflow leading to buffer overflow
https://notcve.org/view.php?id=CVE-2016-2324
Integer overflow in Git before 2.7.4 allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, which triggers a heap-based buffer overflow. Desboradmiento de entero en Git en versiones anteriores a 2.7.4 permite a atacantes remotos ejecutar código arbitrario a través de un (1) nombre de archivo grande o (2) muchos árboles anidados, lo que desencadena un desbordamiento de buffer basado en memoria dinámica. An integer truncation flaw and an integer overflow flaw, both leading to a heap-based buffer overflow, were found in the way Git processed certain path information. A remote attacker could create a specially crafted Git repository that would cause a Git client or server to crash or, possibly, execute arbitrary code. • http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183147.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179121.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/180763.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00061.html http://lists.opensuse.org/opensuse-security-announce • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-194: Unexpected Sign Extension •
CVE-2015-8816
https://notcve.org/view.php?id=CVE-2015-8816
The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device. La función hub_activate en drivers/usb/core/hub.c en el Kernel de Linux en versiones anteriores a 4.3.5 no mantiene correctamente una estructura de datos hub-interface, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (acceso a memoria no válido y caída de sistema) o posiblemente tener otro impacto no especificado desenchufando un dispositivo hub USB. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e50293ef9775c5f1cf3fcc093037dd6a8c5684ea http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org •
CVE-2015-7547 – glibc - 'getaddrinfo' Stack Buffer Overflow (PoC)
https://notcve.org/view.php?id=CVE-2015-7547
Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. Múltiples desbordamientos de buffer basado en pila en las funciones (1) send_dg y (2) send_vc en la librería libresolv en la librería GNU C (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes remotos causar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una respuesta DNS manipulada que desencadenan una llamada a la función getaddrinfo con la familia de direcciones AF_UNSPEC o AF_INET6, en relación con la ejecución de "consultas duales A/AAAA DNS" y el módulo libnss_dns.so.2 NSS. A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. • https://www.exploit-db.com/exploits/39454 https://www.exploit-db.com/exploits/40339 https://github.com/fjserna/CVE-2015-7547 https://github.com/cakuzo/CVE-2015-7547 https://github.com/Stick-U235/CVE-2015-7547-Research https://github.com/t0r0t0r0/CVE-2015-7547 https://github.com/babykillerblack/CVE-2015-7547 https://github.com/Amilaperera12/Glibc-Vulnerability-Exploit-CVE-2015-7547 https://github.com/miracle03/CVE-2015-7547-master https://github.com/bluebluelan/CVE-2015-7547 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
CVE-2015-5041 – JDK: J9 JVM allows code to invoke non-public interface methods

The J9 JVM in IBM SDK, Java Technology Edition 6 before SR16 FP20, 6 R1 before SR8 FP20, 7 before SR9 FP30, and 7 R1 before SR3 FP30 allows remote attackers to obtain sensitive information or inject data by invoking non-public interface methods. El JVM J9 en IBM SDK, Java Technology Edition 6 en versiones anteriores a SR16 FP20, 6 R1 en versiones anteriores a SR8 FP20, 7 en versiones anteriores a SR9 FP30 y 7 R1 en versiones anteriores a SR3 FP30 permite a atacantes remotos obtener información sensible o inyectar datos invocando a métodos de interfaz no públicos. • http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00032.html http://www-01.ibm.com/support/docview.wss?uid=swg1IV72872 http://www-01.ibm.com/support/docview.wss?uid=swg21974194 http://www.securityfocus.com/bid/82451 https://access.redhat.com/errata/RHSA-201 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •
