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.

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.

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

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.

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.

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.

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

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

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

xlockmore before 5.43 'dclock' security bypass vulnerability

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.

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

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.

A stack-based buffer overflow flaw was found in the way FuseISO, a FUSE module to mount ISO filesystem images, performed expanding of directories portions for absolute path filename entries. A remote attacker could provide a specially-crafted ISO file that, when mounted via fuseiso tool would lead to fuseiso binary crash or, potentially, arbitrary code execution with the privileges of the user running the fuseiso executable.

Note: Since the fuseiso binary on Fedora is compiled with FORTIFYSOURCE protection enabled, this flaw would allow an attacker to cause fuseiso binary to crash only.

An integer overflow, leading to heap-based buffer overflow flaw was found in the way FuseISO, a FUSE module to mount ISO filesystem images, performed reading of certain ZF blocks of particular inode. A remote attacker could provide a specially-crafted ISO file that, when mounted via fuseiso tool would lead to fuseiso binary crash.

Michael Scherer reported that the fedora-business-cards script used /tmp/fedora-business-cards-buffer.svg as a temporary file, which could be used in symlink attacks to overwrite the contents of a file with write permissions to the person running fedora-business-cards.

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.

A flaw was found in the way message freeing on connection cleanup was handled under certain error conditions. A remote user able to issue commands to libvirt daemon could use this flaw to crash libvirtd or, potentially, escalate their privilages to that of libvirtd process.

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.

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.

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.

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.

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.

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.

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.

Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on 64-bit systems where sizeof(sizet) is equal to 8. In the archivewritezipdata() function in libarchive/archivewritesetformatzip.c, the "s" parameter is of type sizet (64 bit, unsigned) and is cast to a 64 bit signed integer. If "s" is larger than MAXINT, it will not be set to "zip->remainingdatabytes" even though it is larger than "zip->remainingdatabytes", which leads to a buffer overflow when calling deflate().

This can lead to a segfault in an application that uses libarchive to create ZIP archives.

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.

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 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).
