CVE-2014-3468 – libtasn1: asn1_get_bit_der() can return negative bit length
https://notcve.org/view.php?id=CVE-2014-3468
The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data. La función asn1_get_bit_der en GNU Libtasn1 anterior a 3.6 no informa debidamente de un error cuando una longitud de bit negativa está identificada, lo que permite a atacantes dependientes de contexto causar acceso fuera de rango a través de datos ASN.1 manipulados. • http://advisories.mageia.org/MGASA-2014-0247.html http://git.savannah.gnu.org/cgit/libtasn1.git/commit/?id=1c3ccb3e040bf13e342ee60bc23b21b97b11923f http://linux.oracle.com/errata/ELSA-2014-0594.html http://linux.oracle.com/errata/ELSA-2014-0596.html http://lists.gnu.org/archive/html/help-libtasn1/2014-05/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00015.html http://rhn.redhat.com/err • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-131: Incorrect Calculation of Buffer Size •
CVE-2014-3469 – libtasn1: asn1_read_value_type() NULL pointer dereference
https://notcve.org/view.php?id=CVE-2014-3469
The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument. Las funciones (1) asn1_read_value_type y (2) asn1_read_value en GNU Libtasn1 anterior a 3.6 permite a atacantes dependientes de contexto causar una denegación de servicio (referencia de puntero nulo y caída) a través de un valor nulo en un argumento ivalue. • http://advisories.mageia.org/MGASA-2014-0247.html http://linux.oracle.com/errata/ELSA-2014-0594.html http://linux.oracle.com/errata/ELSA-2014-0596.html http://lists.gnu.org/archive/html/help-libtasn1/2014-05/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-06/msg00015.html http://rhn.redhat.com/errata/RHSA-2014-0594.html http://rhn.redhat.com/errata/RHSA-2014-0596.html http:/ • CWE-476: NULL Pointer Dereference •
CVE-2014-0160 – OpenSSL Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2014-0160
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Las implementaciones de (1) TLS y (2) DTLS en OpenSSL 1.0.1 en versiones anteriores a 1.0.1g no manejan adecuadamente paquetes Heartbeat Extension, lo que permite a atacantes remotos obtener información sensible desde la memoria de proceso a través de paquetes manipulados que desencadenan una sobrelectura del buffer, según lo demostrado mediante la lectura de claves privadas, relacionado con d1_both.c y t1_lib.c, también conocido como bug Heartbleed. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. • https://www.exploit-db.com/exploits/32764 https://www.exploit-db.com/exploits/32791 https://www.exploit-db.com/exploits/32998 https://www.exploit-db.com/exploits/32745 https://github.com/0x90/CVE-2014-0160 https://github.com/jdauphant/patch-openssl-CVE-2014-0160 https://github.com/caiqiqi/OpenSSL-HeartBleed-CVE-2014-0160-PoC https://github.com/obayesshelton/CVE-2014-0160-Scanner https://github.com/MrE-Fog/CVE-2014-0160-Chrome-Plugin https://github.com/Xyl2k/CVE-2014 • CWE-125: Out-of-bounds Read CWE-201: Insertion of Sensitive Information Into Sent Data •
CVE-2014-2497 – gd: NULL pointer dereference in gdImageCreateFromXpm()
https://notcve.org/view.php?id=CVE-2014-2497
The gdImageCreateFromXpm function in gdxpm.c in libgd, as used in PHP 5.4.26 and earlier, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted color table in an XPM file. La función gdImageCreateFromXpm en gdxpm.c en libgd, utilizado en PHP 5.4.26 y anteriores, permite a atacantes remotos causar una denegación de servicio (referencia a puntero cero y caída de aplicación) a través de una tabla de color manipulada en un archivo XPM. A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. • http://advisories.mageia.org/MGASA-2014-0288.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-07/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-07/msg00002.html http://rhn.redhat.com/errata/RHSA-2014-1326.html http://rhn.redhat.com/errata/RHSA-2014-1327.html http://rhn.redhat.com/errata/RHSA-2014-1765.html http://rhn.redhat.com/errata/RHSA-2014-1766.html http://se • CWE-476: NULL Pointer Dereference •
