CVSS: 7.5EPSS: 81%CPEs: 58EXPL: 0CVE-2015-7704 – ntp: disabling synchronization via crafted KoD packet
https://notcve.org/view.php?id=CVE-2015-7704
The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. El cliente ntpd en NTP 4.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio empleando una serie de mensajes "KOD" manipulados. It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. A remote attacker could use this flaw to send a crafted Kiss-of-Death packet to an ntpd client that would increase the client's polling interval value, and effectively disable synchronization with the server. • http://bugs.ntp.org/show_bug.cgi?id=2901 http://rhn.redhat.com/errata/RHSA-2015-1930.html http://rhn.redhat.com/errata/RHSA-2015-2520.html http://support.ntp.org/bin/view/Main/NtpBug2901 http://support.ntp.org/bin/view/Main/SecurityNotice#October_2015_NTP_4_2_8p4_Securit http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/77280 http://www.securitytracker.com/id/1 • CWE-20: Improper Input Validation •
CVSS: 5.8EPSS: 0%CPEs: 34EXPL: 0CVE-2014-8160 – kernel: iptables restriction bypass if a protocol handler kernel module not loaded
https://notcve.org/view.php?id=CVE-2014-8160
net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers. net/netfilter/nf_conntrack_proto_generic.c en el kernel de Linux anterior a 3.18 genera entradas conntrack incorrectas durante el manejo de ciertos juegos de reglas iptables para los protocolos SCTP, DCCP, GRE, y UDP-Lite, lo que permite a atacantes remotos evadir las restricciones de acceso a través de paquetes con números de puertos rechazados. A flaw was found in the way the Linux kernel's netfilter subsystem handled generic protocol tracking. As demonstrated in the Stream Control Transmission Protocol (SCTP) case, a remote attacker could use this flaw to bypass intended iptables rule restrictions when the associated connection tracking module was not loaded on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=db29a9508a9246e77087c5531e45b2c88ec6988b http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://rhn.redhat.com/errata/RHSA&# • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2014-6055
Multiple stack-based buffer overflows in the File Transfer feature in rfbserver.c in LibVNCServer 0.9.9 and earlier allow remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a (1) long file or (2) directory name or the (3) FileTime attribute in a rfbFileTransferOffer message. Múltiples desbordamientos de buffer basado en pila en la caracteristica File Transfer en rfbserver.c en LibVNCServer 0.9.9 y anteriores permiten a usuarios remotos autenticados causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un (1) fichero largo o (2) nombre de directorio o el (3) atributo FileTime en un mensaje rfbFileTransferOffer. Two stack-based buffer overflow flaws were found in the way LibVNCServer handled file transfers. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client. • http://lists.fedoraproject.org/pipermail/package-announce/2014-October/139654.html http://lists.fedoraproject.org/pipermail/package-announce/2014-September/139445.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00022.html http://rhn.redhat.com/errata/RHSA-2015-0113.html http://seclists.org/oss-sec/2014/q3/639 http://secunia.com/advisories/61506 http://www.debian.org/security/2014/dsa-3081 http://www.ocert.org/advisories/ocert-2014-007.html http://www.openwall.com/lists& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2014-6051
Integer overflow in the MallocFrameBuffer function in vncviewer.c in LibVNCServer 0.9.9 and earlier allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via an advertisement for a large screen size, which triggers a heap-based buffer overflow. Desbordamiento de enteros en la función MallocFrameBuffer en vncviewer.c en LibVNCServer 0.9.9 y anteriores permite a servidores remotos VNC causar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un anuncio para un tamaño grande de pantalla, lo que provoca un desbordamiento de buffer basado en memoria dinámica. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way screen sizes were handled by LibVNCServer. A malicious VNC server could use this flaw to cause a client to crash or, potentially, execute arbitrary code in the client. • http://lists.fedoraproject.org/pipermail/package-announce/2014-October/139654.html http://lists.fedoraproject.org/pipermail/package-announce/2014-September/139445.html http://lists.opensuse.org/opensuse-updates/2015-12/msg00022.html http://rhn.redhat.com/errata/RHSA-2015-0113.html http://seclists.org/oss-sec/2014/q3/639 http://secunia.com/advisories/61506 http://www.debian.org/security/2014/dsa-3081 http://www.ocert.org/advisories/ocert-2014-007.html http://www.openwall.com/lists& • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
