https://notcve.org/view.php?id=CVE-2016-5844
Integer overflow in the ISO parser in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a crafted ISO file. Desbordamiento de entero en el analizador ISO en libarchive en versiones anteriores a 3.2.1 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un archivo ISO manipulado. Undefined behavior (signed integer overflow) was discovered in libarchive, in the ISO parser. A crafted file could potentially cause denial of service. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.debian.org/security/2016/dsa-3657 http://www.openwall.com/lists/oss-security/2016/06/23/6 http://www.openwall.com/lists/oss-security/2016/06/24/4 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/91808 http://www.securityt • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2016-4809
The archive_read_format_cpio_read_header function in archive_read_support_format_cpio.c in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) via a CPIO archive with a large symlink. La función archive_read_format_cpio_read_header en archive_read_support_format_cpio.c en libarchive en versiones anteriores a 3.2.1 permite a atacantes remotos provocar denegación de servicio (caída de aplicación) a través de un archivo CPIO con un enlace simbólico grande. A vulnerability was found in libarchive. A specially crafted cpio archive containing a symbolic link to a ridiculously large target path can cause memory allocation to fail, resulting in any attempt to view or extract the archive crashing. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.debian.org/security/2016/dsa-3657 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/91813 https://bugzilla.redhat.com/show_bug.cgi?id=1347084 https://github.com/libarchive/libarchive/commit/fd7e0c02 https://github.com/libarchive/libarchive/issues/705 https://security.gentoo.org/glsa/201701-03 https://access • CWE-20: Improper Input Validation CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
CVSS: 9.8EPSS: 15%CPEs: 39EXPL: 0CVE-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 •
CVSS: 5.5EPSS: 0%CPEs: 45EXPL: 0CVE-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 •
