drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure that certain length values are sufficiently large, which allows remote attackers to cause a denial of service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to the (1) ozusbrx and (2) ozusbhandleepdata functions.

The (1) jdom.rb and (2) rexml.rb components in Active Support in Ruby on Rails before 3.2.22, 4.1.x before 4.1.11, and 4.2.x before 4.2.2, when JDOM or REXML is enabled, allow remote attackers to cause a denial of service (SystemStackError) via a large XML document depth.
Fixed bug (Uninitialized pointer in pharmakedirstream()). (CVE-2016-4343)
A flaw was reported in IcedTea-web plugin where certain events attached to an applet, when triggered, could lead to a heap-based buffer overflow, resulting in possible information leak, crash, or code execution.
Multiple cross-site scripting (XSS) vulnerabilities in Cacti 0.8.8b and earlier allow remote attackers to inject arbitrary web script or HTML via (1) the step parameter to install/index.php or (2) the id parameter to cacti/host.php.
Description of problem:
There are serveral problems with the way Jython creates class cache files, potentially leading to arbitrary code execution or information disclosure.
(umask 000; jython -c 'import xmllib') ls -l '/usr/share/jython/Lib/xmllib$py.class' -rw-rw-rw-. 1 root root 52874 Apr 3 17:24 /usr/share/jython/Lib/xmllib$py.class
Jython does not explicitly set permissions of the class files; therefore with weak umask it creates world-writable files, or discloses sensitive data that would be in a non-world-readable package file.
Also, the package writes to /usr/share, which it shouldn't; /var/cache would be more appropriate, but would still lead to a possibility of a content disclosure.
The only really portable and secure way to cache class files would be a directory in user's home with 0700 permissions.
It is currently even not possible to easily disable the caching, since the configuration file is not marked with %config and resides in /usr/share instead of /etc.
Version-Release number of selected component (if applicable):
jython-2.2.1-4.8.el6.x8664
It was reported that hivex [1], a library that can read and write hive files (undocumented binary files that Windows uses to store the Windows Registry on disk), did not properly handle small-sized hive files. An attacker able to supply a hive file of a small size to an application using the hivex library could use this flaw to read, and possibly write, up to 4095 bytes beyond the end of the allocated buffer, potentially resulting in arbitrary code execution with the with the privileges of the user running that application.
This issue has been fixed in upstream version 3.11 of hivex. Upstream patches are available at:

Directory traversal vulnerability in libraries/errorreport.lib.php in the error-reporting feature in phpMyAdmin 4.1.x before 4.1.14.7 and 4.2.x before 4.2.12 allows remote authenticated users to obtain potentially sensitive information about a file's line count via a crafted parameter.

automount 5.0.8, when a program map uses certain interpreted languages, uses the calling user's USER and HOME environment variable values instead of the values for the user used to run the mapped program, which allows local users to gain privileges via a Trojan horse program in the user home directory.
Multiple cross-site scripting (XSS) vulnerabilities in phpMyAdmin 4.0.x before 4.0.10.5, 4.1.x before 4.1.14.6, and 4.2.x before 4.2.10.1 allow remote authenticated users to inject arbitrary web script or HTML via a crafted (1) database name or (2) table name, related to the libraries/DatabaseInterface.class.php code for SQL debug output and the js/serverstatusmonitor.js code for the server monitor page.
Directory traversal vulnerability in actionpack/lib/actiondispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.20, 4.0.x before 4.0.11, 4.1.x before 4.1.7, and 4.2.x before 4.2.0.beta3, when servestaticassets is enabled, allows remote attackers to determine the existence of files outside the application root via a /..%2F sequence.
Directory traversal vulnerability in actionpack/lib/actiondispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.21, 4.0.x before 4.0.12, 4.1.x before 4.1.8, and 4.2.x before 4.2.0.beta4, when servestaticassets is enabled, allows remote attackers to determine the existence of files outside the application root via vectors involving a \ (backslash) character, a similar issue to CVE-2014-7818.
The mdcheck script of the mdadm package for openSUSE 13.2 prior to version 3.3.1-5.14.1 does not properly sanitize device names, which allows local attackers to execute arbitrary commands as root.
A cross-site scripting (XSS) vulnerability in the view operations page in phpMyAdmin 4.1.x before 4.1.14.3 and 4.2.x before 4.2.7.1 allows remote authenticated users to inject arbitrary web script or HTML via a crafted view name, related to js/functions.js.

GNU Parallel before 20150522 (Nepal), when using (1) --cat or (2) --fifo with --sshlogin, allows local users to write to arbitrary files via a symlink attack on a temporary file.
The NaClSandbox::InitializeLayerTwoSandbox function in components/nacl/loader/sandboxlinux/naclsandboxlinux.cc in Google Chrome before 42.0.2311.90 does not have RLIMITAS and RLIMITDATA limits for Native Client (aka NaCl) processes, which might make it easier for remote attackers to conduct row-hammer attacks or have unspecified other impact by leveraging the ability to run a crafted program in the NaCl sandbox.
Libcontainer 1.6.0, as used in Docker Engine, allows local users to escape containerization ("mount namespace breakout") and write to arbitrary file on the host system via a symlink attack in an image when respawning a container.
It was reported that polkit has a bug, that leads to a minor denial of service, or code execution/privilege escalation. The only privilege necessary is ability to send D-Bus messages, not even necessarily directly to polkitd (usually privileged services ask polkitd for authorization based of a client request: client<->D-Bus<->service<->D-Bus<->polkitd); the attacker does not need special polkit status. This bug allows a local user (a person on a multi-user system, or a daemon account after successfully attacking a daemon over the network) to corrupt memory of polkitd. Corrupting polkitd memory can lead to a crash (known to happen), which is a minor DoS: a specific request being handled during the crash will not get a reply, but polkitd will then be automatically started when next polkit request arrives. In general corrupting memory can lead to arbitrary code execution as polkitd (no proof of concept exists but I can see no reason for this to be impossible), controlling polkitd allows the attacker to grant to anyone access to any polkit-controlled service, including the ability to run any command as root via pkexec.
