CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 3CVE-2016-5418 – libarchive: Archive Entry with type 1 (hardlink), but has a non-zero data size file overwrite
https://notcve.org/view.php?id=CVE-2016-5418
The sandboxing code in libarchive 3.2.0 and earlier mishandles hardlink archive entries of non-zero data size, which might allow remote attackers to write to arbitrary files via a crafted archive file. El código sandboxing en libarchive 3.2.0 y versiones anteriores no maneja adecuadamente entradas de archivo de vínculo físico de datos de tamaño distinto de cero, lo que podría permitir a atacantes remotos escribir a archivos arbitrarios a través de un archivo manipulado. A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive. • http://rhn.redhat.com/errata/RHSA-2016-1844.html http://rhn.redhat.com/errata/RHSA-2016-1850.html http://www.openwall.com/lists/oss-security/2016/08/09/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/93165 https://access.redhat.com/errata/RHSA-2016:1852 https://access.redhat.com/errata/RHSA-2016:1853 https://bugzilla.redhat.com/show_bug.cgi?id=1362601 https://gist.github.com/anonymous/e48209b03f1dd9625a992717e7b8 • CWE-19: Data Processing Errors CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 8.1EPSS: 94%CPEs: 18EXPL: 0CVE-2016-5388 – Tomcat: CGI sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5388
Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability. Apache Tomcat, en versiones 7.x hasta la 7.0.70 y versiones 8.x hasta la 8.5.4, cuando el Servlet CGI está habilitado, sigue la sección 4.1.18 de RFC 3875 y, por lo tanto, no protege aplicaciones ante la presencia de datos de cliente no fiables en la variable de entorno HTTP_PROXY. Esto podría permitir que atacantes remotos redirijan el tráfico HTTP saliente de una aplicación a un servidor proxy arbitrario mediante una cabecera Proxy manipulada en una petición HTTP. Esto también se conoce como problema "httpoxy". • http://lists.opensuse.org/opensuse-updates/2016-09/msg00025.html http://rhn.redhat.com/errata/RHSA-2016-1624.html http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/91818 http://www.securitytracker.com/id/ • CWE-20: Improper Input Validation CWE-284: Improper Access Control •

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.

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 •
