CVE-2016-2178 – openssl: Non-constant time codepath followed for certain operations in DSA implementation
https://notcve.org/view.php?id=CVE-2016-2178
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. La función dsa_sign_setup en crypto/dsa/dsa_ossl.c en OpenSSL hasta la versión 1.0.2h no asegura correctamente la utilización de operaciones de tiempo constante, lo que facilita a usuarios locales descubrir una clave privada DSA a través de un ataque de sincronización de canal lateral. It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. • http://eprint.iacr.org/2016/594.pdf http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org& • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
CVE-2016-2177 – openssl: Possible integer overflow vulnerabilities in codebase
https://notcve.org/view.php?id=CVE-2016-2177
OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer boundary checks, which might allow remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact by leveraging unexpected malloc behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c. OpenSSL hasta la versión 1.0.2h no utiliza correctamente la aritmética de puntero para comprobaciones de límites de buffer de memoria dinámica, lo que podría permitir a atacantes remotos provocar una denegación de servicio (desbordamiento de entero y caída de aplicación) o posiblemente tener otro impacto no especificado aprovechando un comportamiento malloc no esperado, relacionado con s3_srvr.c, ssl_sess.c, y t1_lib.c. Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-190: Integer Overflow or Wraparound •
CVE-2015-8896 – ImageMagick: Integer truncation vulnerability in coders/pict.c

Integer truncation issue in coders/pict.c in ImageMagick before 7.0.5-0 allows remote attackers to cause a denial of service (application crash) via a crafted .pict file. Problema de truncamiento de entero en coders/pict.c en ImageMagick en versiones anteriores a 7.0.5-0 permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) a través de un archivo .pict manipulado. • http://www.openwall.com/lists/oss-security/2015/10/07/2 http://www.openwall.com/lists/oss-security/2015/10/08/3 http://www.openwall.com/lists/oss-security/2016/06/02/13 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/91027 https://access.redhat.com/errata/RHSA-2016:1237 https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1448803 https://github.com/ImageMagick/ImageMagick/commit/0f6fc2d5bf8f500820c3dbcf0d23ee14 •
CVE-2016-5118 – ImageMagick: Remote code execution via filename
https://notcve.org/view.php?id=CVE-2016-5118
The OpenBlob function in blob.c in GraphicsMagick before 1.3.24 and ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename. La función OpenBlob en blob.c en GraphicsMagick en versiones anteriores a 1.3.24 y ImageMagick permite a atacantes remotos ejecutar código arbitrario a través del caractér | (tubería) en el inicio del nombre de archivo. It was discovered that ImageMagick did not properly sanitize certain input before using it to invoke processes. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would lead to arbitrary execution of shell commands with the privileges of the user running the application. • http://git.imagemagick.org/repos/ImageMagick/commit/40639d173aa8c76b850d625c630b711fee4dcfb8 http://hg.code.sf.net/p/graphicsmagick/code/file/41876934e762/ChangeLog http://hg.code.sf.net/p/graphicsmagick/code/rev/ae3928faa858 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg0002 • CWE-20: Improper Input Validation •
