Buffer overflow in the DumpSysVar function in var.c in Remind before 3.1.15 allows attackers to have unspecified impact via a long name.

Use-after-free vulnerability in validators/DTD/DTDScanner.cpp in Apache Xerces C++ 3.1.3 and earlier allows context-dependent attackers to have unspecified impact via an invalid character in an XML document.

LibreSSL. Multiple issues were addressed by updating to libressl version 2.6.4.

Heap-based buffer overflow in the gdkpixbufflip function in gdk-pixbuf-scale.c in gdk-pixbuf 2.30.x allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted BMP file.

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.

Fixed bug (Uninitialized pointer in pharmakedirstream()). (CVE-2016-4343)

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.

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.

The asn1getsequenceof function in library/asn1parse.c in PolarSSL 1.0 through 1.2.12 and 1.3.x through 1.3.9 does not properly initialize a pointer in the asn1sequence linked list, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted ASN.1 sequence in a certificate.

Sergey "Shnatsel" Davidoff reported a heap-based buffer overflow in Vala Gstreamer bindings in the Gst.MapInfo() function. Further details are available in the following Red Hat bug:

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.

A vulnerability was found in cairo. A maliciously crafted file can cause out of bounds read in fillxrgb32lerpopaquespans function in cairo, thus crashing the software.

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.

Directory traversal vulnerability in libraries/gis/GISFactory.class.php in the GIS editor in phpMyAdmin 4.0.x before 4.0.10.6, 4.1.x before 4.1.14.7, and 4.2.x before 4.2.12 allows remote authenticated users to include and execute arbitrary local files via a crafted geometry-type parameter.

Directory traversal vulnerability in the gcabfolderextract function in libgcab/gcab-folder.c in gcab 0.4 allows remote attackers to write to arbitrary files via crafted path in a CAB file, as demonstrated by "\tmp\moo."

Unspecified vulnerability in vsftpd 3.0.2 and earlier allows remote attackers to bypass access restrictions via unknown vectors, related to denyfile parsing.

jcc.c in Privoxy before 3.0.23 allows remote attackers to cause a denial of service (abort) via a crafted chunk-encoded body.

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.

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.

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:

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.

Initially reported in https://bugzilla.redhat.com/showbug.cgi?id=910262 The patches are attached.

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

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 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.

GNU patch 2.7.1 allows remote attackers to write to arbitrary files via a symlink attack in a patch file.

Cross-site scripting (XSS) vulnerability in org/chromium/chrome/browser/UrlUtilities.java in Google Chrome before 44.0.2403.89 on Android allows remote attackers to inject arbitrary web script or HTML via a crafted intent: URL, as demonstrated by a trailing alert(document.cookie);// substring, aka "Universal XSS (UXSS)."

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.
