A type conversion flaw leading to an out-of-bounds heap buffer read was found in the way libpng, a library of functions for manipulation PNG image format files, performed expansion of certain iCCP, iTXt, and zTXt PNG image file chunks.

A remote attacker could provide a specially-crafted Portable Network Graphics (PNG) image file, which once opened in an application, linked against libpng, could lead to denial of service or in some cases, execution of arbitrary code with permission of the user running such an application.

Upstream patch: http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng;a=commitdiff;h=a8c319a2b281af68f7ca0e2f9a28ca57b44ceb2b#patch3

ZendXmlRpc in Zend Framework 1.x before 1.11.12 and 1.12.x before 1.12.0 does not properly handle SimpleXMLElement classes, which allows remote attackers to read arbitrary files or create TCP connections via an external entity reference in a DOCTYPE element in an XML-RPC request, aka an XML external entity (XXE) injection attack.

python-bugzilla before 0.9.0 does not validate X.509 certificates, which allows man-in-the-middle attackers to spoof Bugzilla servers via a crafted certificate.

The py-bcrypt module before 0.3 for Python does not properly handle concurrent memory access, which allows attackers to bypass authentication via multiple authentication requests, which trigger the password hash to be overwritten.

pip before 1.3 allows local users to overwrite arbitrary files via a symlink attack on a file in the /tmp/pip-build temporary directory.

Cross-site scripting (XSS) vulnerability in Plupload.as in Moxiecode plupload before 1.5.5, as used in WordPress before 3.5.1 and other products, allows remote attackers to inject arbitrary web script or HTML via the id parameter.

A buffer overflow flaw was found in the way e1000 emulated device driver of QEMU, a FAST! processor emulator, processed received large e1000 packets, when the SBP and LPE flags were disabled. If the underlying network was configured to allow large (jumbo) packets, a remote attacker could use this flaw to cause relevant guest in question to crash (DoS) or, potentially, the attacker could use this flaw to execute arbitrary code on the guest system with the kernel level privilege.

The rasterization process in Inkscape before 0.48.4 allows local users to read arbitrary files via an external entity in a SVG file, aka an XML external entity (XXE) injection attack.

gnome-system-log polkit policy allows arbitrary files on the system to be read

xlockmore before 5.43 'dclock' security bypass vulnerability

A Security Bypass vulnerability exists in PolarSSL 0.99pre4 through 1.1.1 due to a weak encryption error when generating Diffie-Hellman values and RSA keys.

Buffer overflow in ngxhttpmp4module.c in the ngxhttpmp4module module in nginx 1.0.7 through 1.0.14 and 1.1.3 through 1.1.18, when the mp4 directive is used, allows remote attackers to cause a denial of service (memory overwrite) or possibly execute arbitrary code via a crafted MP4 file.

Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows remote authenticated users with agent SSL keys and file-creation permissions on the puppet master to execute arbitrary commands by creating a file whose full pathname contains shell metacharacters, then performing a filebucket request.

Moodle before 2.2.2 has an external enrolment plugin context check issue where capability checks are not thorough

A flaw was reported [1] in nginx versions prior to 1.0.14 and 1.1.17 where contents of previously freed memory could be sent to a client if an upstream server returned a specially crafted HTTP response. This could potentially leak sensitive information to the HTTP client.

This has been corrected upstream [2],[3] and a patch [4] is available for earlier versions of nginx.

Moodle before 2.2.2 default settings allowed all repositories to be viewable by all authenticated users.

Moodle before 2.2.2 has a course information leak in gradebook where users are able to see hidden grade items in export

Moodle has a database activity export permission issue where the export function of the database activity module exports all entries even those from groups the user does not belong to

Moodle before 2.2.2 is vulnerable to information disclosure because course backups were including users' private files.

Moodle before 2.2.2 has Personal information disclosure, when administrative setting users name display is set to first name only full names are shown in page breadcrumbs.

Moodle before 2.2.2: Course information leak via hidden courses being displayed in tag search results

Moodle before 2.2.2 has a permission issue in Forum Subscriptions where unenrolled users can subscribe/unsubscribe via mod/forum/index.php

Moodle before 2.2.2 has a password and web services issue where when the user profile is updated the user password is reset if not specified.

Moodle before 2.2.2 has users' private files included in course backups

It was reported that the XML files parser of ModSecurity, a security module for the Apache HTTP Server, was vulnerable to XML External Entity attacks. A remote attacker could provide a specially-crafted XML file that, when processed might lead to local files disclosure or, potentially, excessive resources (memory, CPU) consumption.

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 does not allow extensions to prevent password changes without using both Special:PasswordReset and Special:ChangePassword, which allows remote attackers to bypass the intended restrictions of an extension that only implements one of these blocks.

A cross-site scripting (XSS) vulnerability in MantisBT 1.2.14 allows remote attackers to inject arbitrary web script or HTML via a version, related to deleting a version.

MantisBT 1.2.12 before 1.2.15 allows authenticated users to by the workflow restriction and close issues.

user/view.php in Moodle through 2.1.10, 2.2.x before 2.2.8, 2.3.x before 2.3.5, and 2.4.x before 2.4.2 does not enforce the forceloginforprofiles setting, which allows remote attackers to obtain sensitive course-profile information by leveraging the guest role, as demonstrated by a Google search.

A denial of service flaw was found in the way ruby-openid, a library for verifying and serving OpenID identities, performed processing of certain XML files. An OpenID provider could provide a specially-crafted XML file that, when processed would lead to excessive CPU consumption (denial of service).
