The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. El protocolo TLS 1.2 y anteriores, cuando una suite de cifrado DHE_EXPORT está habilitada en un servidor pero no en un cliente, no transporta una elección DHE_EXPORT, lo que permite a atacantes man-in-the-middle realizar ataques de degradación del cifrado mediante la rescritura de un ClientHello con DHE remplazado por DHE_EXPORT y posteriormente la rescritura de un ServerHello con DHE_EXPORT remplazado por DHE, también conocido como el problema 'Logjam'. A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange (for both export and non-export grade cipher suites). An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. • http://aix.software.ibm.com/aix/efixes/security/sendmail_advisory2.asc http://fortiguard.com/advisory/2015-07-09-cve-2015-1793-openssl-alternative-chains-certificate-forgery http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2015-008.txt.asc http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04876402 http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04949778 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10681 http://kb.juniper.net/InfoC • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

GStreamer before 1.4.5, as used in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 on Linux, allows remote attackers to cause a denial of service (buffer over-read and application crash) or possibly execute arbitrary code via crafted H.264 video data in an m4v file. GStreamer anterior a 1.4.5, utilizado en Mozilla Firefox anterior a 38.0, Firefox ESR 31.x anterior a 31.7, y Thunderbird anterior a 31.7 en Linux, permite a atacantes remotos causar una denegación de servicio (sobrelectura de buffer y caída de aplicación) o posiblemente ejecutar código arbitrario a través de datos de vídeo H.264 manipulados en un fichero m4v. • http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00000.html http://rhn.redhat.com/errata/RHSA-2015-0988.html http://rhn.redhat.com/errata/RHSA-2015-1012.html http://www.debian.org/security/2015/dsa-3225 http://www.debian.org/security/2015/dsa-3260 http://www.debian.org/security/2015/dsa-3264 http://www.mozilla. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Mozilla Firefox before 36.0.4, Firefox ESR 31.x before 31.5.3, and SeaMonkey before 2.33.1 allow remote attackers to bypass the Same Origin Policy and execute arbitrary JavaScript code with chrome privileges via vectors involving SVG hash navigation. Mozilla Firefox anterior a 36.0.4, Firefox ESR 31.x anterior a 31.5.3, y SeaMonkey anterior a 2.33.1 permiten a atacantes remotos evadir Same Origin Policy y ejecutar código JavaScript arbitrario con privilegios chrome a través de vectores que involucran la navegación por hashes de SVG. This vulnerability allows remote attackers to bypass the same-origin policy on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of SVG format content navigation. By using a DOMAttrModified mutation event listener, an attacker can inject an arbitrary URL into the history, and cause Firefox to break the same-origin isolation policy. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00035.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00096.html http://rhn.redhat.com/errata/RHSA-2015-0718.html http://www.debian.org/security/2015/dsa-3201 http://www.mozilla.org/security/announce/2015/mfsa2015-28.html http://www.oracle.com/technetwork/topics/secu • CWE-264: Permissions, Privileges, and Access Controls •

The asm.js implementation in Mozilla Firefox before 36.0.3, Firefox ESR 31.x before 31.5.2, and SeaMonkey before 2.33.1 does not properly determine the cases in which bounds checking may be safely skipped during JIT compilation and heap access, which allows remote attackers to read or write to unintended memory locations, and consequently execute arbitrary code, via crafted JavaScript. La implementación asm.js en Mozilla Firefox anterior a 36.0.3, Firefox ESR 31.x anterior a 31.5.2, y SeaMonkey anterior a 2.33.1 no determina correctamente los casos en los que los rangos de comprobación pueden saltase con seguridad durante la compilación JIT y el acceso a la memoria dinámica, lo que permite a atacantes remotos leer o escribir en localizaciones de memoria no intencionadas, y como consecuencia ejecutar código arbitrario, a través de JavaScript manipulado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of heap access bounds checking. A specially crafted typed array can eliminate bounds checks for heap accesses. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00035.html http://lists.opensuse.org/opensuse-updates/2015-03/msg00096.html http://rhn.redhat.com/errata/RHSA-2015-0718.html http://www.debian.org/security/2015/dsa-3201 http://www.mozilla.org/security/announce/2015/mfsa2015-29.html http://www.oracle.com/technetwork/topics/secu • CWE-17: DEPRECATED: Code CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
