CVE-2015-3405 – ntp: ntp-keygen may generate non-random symmetric keys on big-endian systems
https://notcve.org/view.php?id=CVE-2015-3405
ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys. ntp-keygen en ntp en versiones 4.2.8px anteriores a la 4.2.8p2-RC2 y en versiones 4.3.x anteriores a la 4.3.12 no genera claves MD5 con la suficiente entropía en máquinas big endian cuando el byte de menor orden de la variable temp se sitúa entre 0x20 y 0x7f y no #. Esto podría permitir que atacantes remotos obtengan el valor de las claves MD5 generadas mediante un ataque de fuerza bruta con las 93 claves posibles. A flaw was found in the way the ntp-keygen utility generated MD5 symmetric keys on big-endian systems. An attacker could possibly use this flaw to guess generated MD5 keys, which could then be used to spoof an NTP client or server. • http://bk1.ntp.org/ntp-stable/?PAGE=patch&REV=55199296N2gFqH1Hm5GOnhrk9Ypygg http://lists.fedoraproject.org/pipermail/package-announce/2015-April/156248.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00000.html http://rhn.redhat.com/errata/RHSA-2015-1459.html http://rhn.redhat.com/errata/RHSA-2015-2231.html http://www.debian.org/security/2015/dsa-3223 http://www.debian.org/security/2015/dsa-3388 http://www.openwall.com/lists/oss-security/2015/04/23/14 http& • CWE-330: Use of Insufficiently Random Values CWE-331: Insufficient Entropy •
CVE-2015-3209 – qemu: pcnet: multi-tmd buffer overflow in the tx path
https://notcve.org/view.php?id=CVE-2015-3209
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. Desbordamiento de buffer basado en memoria dinámica en el controlador PCNET en QEMU permite a atacantes remotos ejecutar código arbitrario mediante el envío de un paquete con el juego TXSTATUS_STARTPACKET y posteriormente un paquete manipulado con el juego TXSTATUS_DEVICEOWNS. A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10698 http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160669.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160677.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2015-4106
https://notcve.org/view.php?id=CVE-2015-4106
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors. QEMU no restringe correctamente el acceso a escritura al espacio PCI config para ciertos dispositivos PCI pass-through, lo que podría permitir a invitados x86 HVM locales obtener privilegios, causar una denegación de servicio (caída de host), obtener información sensible o posiblemente tener otro impacto no especificado a través de vectores desconocidos. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce • CWE-863: Incorrect Authorization •
CVE-2015-8779 – glibc: Unbounded stack allocation in catopen function
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. 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 •
CVE-2014-9761 – glibc: Unbounded stack allocation in nan* functions
https://notcve.org/view.php?id=CVE-2014-9761
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function. Múltiples desbordamientos de buffer basado en pila en la GNU C Library (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes dependientes del contexto causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbirario a través de un argumento largo en la función (1) nan, (2) nanf o (3) nanl. A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code.
