CVSS: 7.5EPSS: 0%CPEs: 28EXPL: 0CVE-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 •
CVSS: 7.5EPSS: 8%CPEs: 15EXPL: 0CVE-2012-2665 – libreoffice: Multiple heap-based buffer overflows in the XML manifest encryption handling code
https://notcve.org/view.php?id=CVE-2012-2665
Multiple heap-based buffer overflows in the XML manifest encryption tag parsing functionality in OpenOffice.org and LibreOffice before 3.5.5 allow remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Open Document Text (.odt) file with (1) a child tag within an incorrect parent tag, (2) duplicate tags, or (3) a Base64 ChecksumAttribute whose length is not evenly divisible by four. Múltiples desbordamientos de bufer basado en en la funcionalidad de cifrado de manifiesto XML en la etiqueta en OpenOffice.org y LibreOffice anterior a v3.5.5 permite a atacantes remotos causar una denegación de servicio y posiblemente ejecutar código arbitrario a través de un Documento de texto diseñado (. Odt) con el archivo(1) una etiqueta de niño dentro de una etiqueta principal incorrecta, (2) duplicar los tags, o (3) un ChecksumAttribute Base64 cuya longitud no es divisible por cuatro. • http://rhn.redhat.com/errata/RHSA-2012-1135.html http://secunia.com/advisories/50142 http://secunia.com/advisories/50146 http://secunia.com/advisories/50692 http://secunia.com/advisories/60799 http://security.gentoo.org/glsa/glsa-201209-05.xml http://www.debian.org/security/2012/dsa-2520 http://www.gentoo.org/security/en/glsa/glsa-201408-19.xml http://www.libreoffice.org/about-us/security/advisories/cve-2012-2665 http://www.pre-cert.de/advisories/PRE-SA-2012-05&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
