CVE-2016-6325 – tomcat: tomcat writable config files allow privilege escalation
https://notcve.org/view.php?id=CVE-2016-6325
The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 5 hasta la versión 7, JBoss Web Server 3.0 y JBoss EWS 2 utiliza permisos débiles para (1) /etc/sysconfig/tomcat y (2) /etc/tomcat/tomcat.conf, lo que permite a usuarios locales obtener privilegios aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. • http://rhn.redhat.com/errata/RHSA-2016-2045.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://rhn.redhat.com/errata/RHSA-2017-0457.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93478 https://access.redhat.com/errata/RHSA-2017:0455 https://access.redhat.com/errata/RHSA-2017:0456 https://bugzilla.redhat.com/show_bug.cgi?id=1367447 https://access.redhat.com/security/cve/CVE-2016-6325 • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVE-2016-5425 – Apache Tomcat 8/7/6 (RedHat Based Distros) - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2016-5425
The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group. El paquete Tomcat en Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux y posiblemente en otros productos distribuidos por Linux utiliza permisos débiles para /usr/lib/tmpfiles.d/tomcat.conf, lo que permite a usuarios locales obtener privilegios de root aprovechando su pertenencia al grupo tomcat. It was discovered that the Tomcat packages installed configuration file /usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges. Apache Tomcat versions 8, 7, and 6 suffer from a privilege escalation vulnerability on RedHat-based distros. • https://www.exploit-db.com/exploits/40488 http://legalhackers.com/advisories/Tomcat-RedHat-Pkgs-Root-PrivEsc-Exploit-CVE-2016-5425.html http://packetstormsecurity.com/files/139041/Apache-Tomcat-8-7-6-Privilege-Escalation.html http://rhn.redhat.com/errata/RHSA-2016-2046.html http://www.openwall.com/lists/oss-security/2016/10/10/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.securityfocus.com/bid/93472 http://www.securitytracker.com/id/1036979 • CWE-276: Incorrect Default Permissions CWE-284: Improper Access Control •
CVE-2016-7166 – libarchive: Denial of service using a crafted gzip file
https://notcve.org/view.php?id=CVE-2016-7166
libarchive before 3.2.0 does not limit the number of recursive decompressions, which allows remote attackers to cause a denial of service (memory consumption and application crash) via a crafted gzip file. libarchive en versiones anteriores a 3.2.0 no limita el número de descompresiones recursivas, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de memoria y caída de aplicación) a través de un archivo gzip manipulado. A vulnerability was found in libarchive. A specially crafted gzip file can cause libarchive to allocate memory without limit, eventually leading to a crash. • 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/2016/09/08/15 http://www.openwall.com/lists/oss-security/2016/09/08/18 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.securityfocus.com/bid/92901 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207362 https://bugzilla.redhat.com/show_bug.cgi?id=1347086 https://github.com/libarchiv • CWE-399: Resource Management Errors CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-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') •
CVE-2016-5403 – Qemu: virtio: unbounded memory allocation on host via guest leading to DoS
https://notcve.org/view.php?id=CVE-2016-5403
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion. La función virtqueue_pop en hw/virtio/virtio.c en QEMU permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y caida del proceso QUEMU) mediante la presentación de solicitudes sin esperar la finalización. Quick Emulator (QEMU) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement results in unbounded memory allocation on the host controlled by the guest. • http://rhn.redhat.com/errata/RHSA-2016-1585.html http://rhn.redhat.com/errata/RHSA-2016-1586.html http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1652.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn • CWE-400: Uncontrolled Resource Consumption •
