CVE-2016-3627 – libxml2: stack exhaustion while parsing xml files in recovery mode
https://notcve.org/view.php?id=CVE-2016-3627
The xmlStringGetNodeList function in tree.c in libxml2 2.9.3 and earlier, when used in recovery mode, allows context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document. La función xmlStringGetNodeList en tree.c en libxml2.2.9.3 y versiones anteriores, cuando se utiliza en modo de recuperación, permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito, consumo de pila y caída de la aplicación) a través de un docuumento XML manipulado. Missing recursive loop detection checks were found in the xmlParserEntityCheck() and xmlStringGetNodeList() functions of libxml2, causing application using the library to crash by stack exhaustion while building the associated data. An attacker able to send XML data to be parsed in recovery mode could launch a Denial of Service on the application. libxml versions prior to 2.9.3 suffer from a stack overflow vulnerability when parsing a malicious file. • http://lists.opensuse.org/opensuse-updates/2016-05/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00127.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://seclists.org/fulldisclosure/2016/May/10 http://www.openwall.com/lists/oss-security/2016/03/21/2 http://www.openwall.com/lists/oss-security/2016/03/21/3 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016& • CWE-674: Uncontrolled Recursion •
CVE-2016-2105 – openssl: EVP_EncodeUpdate overflow
https://notcve.org/view.php?id=CVE-2016-2105
Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of binary data. Desbordamiento de entero en la función EVP_EncodeUpdate en crypto/evp/encode.c en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria dinámica) a través de una gran cantidad de datos binarios. An integer overflow flaw, leading to a buffer overflow, was found in the way the EVP_EncodeUpdate() function of OpenSSL parsed very large amounts of input data. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-05/ • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
CVE-2016-2108 – openssl: Memory corruption in the ASN.1 encoder
https://notcve.org/view.php?id=CVE-2016-2108
The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the "negative zero" issue. La implementación ASN.1 en OpenSSL en versiones anteriores a 1.0.1o y 1.0.2 en versiones anteriores a 1.0.2c permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento inferior de buffer y corrupción de memoria) a través de un campo ANY en datos serializados manipulados, también conocido como el problema "cero negativo". A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-05/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

CVE-2016-2109 – openssl: ASN.1 BIO handling of large amounts of data
https://notcve.org/view.php?id=CVE-2016-2109
The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in the ASN.1 BIO implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (memory consumption) via a short invalid encoding. La función asn1_d2i_read_bio en crypto/asn1/a_d2i_fp.c en la implementación de ASN.1 BIO en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de una codificación corta no válida. A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00013.h • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •
