Multiple directory traversal vulnerabilities in the (1) twikidraw (action/twikidraw.py) and (2) anywikidraw (action/anywikidraw.py) actions in MoinMoin before 1.9.6 allow remote authenticated users with write permissions to overwrite arbitrary files via unspecified vectors. NOTE: this can be leveraged with CVE-2012-6081 to execute arbitrary code.

Unspecified vulnerability in the SIP implementation in Cisco IOS 12.3 and 12.4 allows remote attackers to execute arbitrary code via a malformed SIP message, aka Bug ID CSCsz48680, the "SIP Message Processing Arbitrary Code Execution Vulnerability."

rubygem-activesupport: Multiple vulnerabilities in parameter parsing in ActionPack

active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.

The ANI parser in Microsoft Windows before 7 on the x86 platform, as used in Internet Explorer and other applications, allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted biClrUsed value in the BITMAPINFO header of a .ANI file.

python-setuptools: easy_install insecure installation mechanism

easy_install in setuptools before 0.7 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to the default use of the product.

The password reset functionality in django.contrib.auth in Django before 1.1.3, 1.2.x before 1.2.4, and 1.3.x before 1.3 beta 1 does not validate the length of a string representing a base36 timestamp, which allows remote attackers to cause a denial of service (resource consumption) via a URL that specifies a large base36 integer.

Cross-site scripting (XSS) vulnerability in Django 1.1.x before 1.1.4 and 1.2.x before 1.2.5 might allow remote attackers to inject arbitrary web script or HTML via a filename associated with a file upload.

The Forms Authentication feature in the ASP.NET subsystem in Microsoft .NET Framework 1.1 SP1, 2.0 SP2, 3.5 SP1, 3.5.1, and 4.0, when sliding expiry is enabled, does not properly handle cached content, which allows remote attackers to obtain access to arbitrary user accounts via a crafted URL, aka "ASP.NET Forms Authentication Ticket Caching Vulnerability."

libxml2: Heap-based buffer overflow when decoding an entity reference with a long name

Heap-based buffer overflow in libxml2, as used in Google Chrome before 16.0.912.75, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

WebKit: use-after-free vulnerability in handling of attribute manipulation

Use-after-free vulnerability in WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Safari before 4.1 on Mac OS X 10.4, and Safari on Apple iPhone OS allows remote attackers to execute arbitrary code or cause a denial of service (application crash), or read the SMS database or other data, via vectors related to "attribute manipulation," as demonstrated by Vincenzo Iozzo and Ralf Philipp Weinmann during a Pwn2Own competition at CanSecWest 2010.

The Graphics Device Interface (GDI) in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly validate user-mode input, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted data, as demonstrated by a large height attribute of an IFRAME element rendered by Safari, aka "GDI Access Violation Vulnerability."

Microsoft Internet Explorer 6 and 7 does not initialize certain data structures during execution of the createElement method, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted JavaScript code, as demonstrated by setting the (1) outerHTML or (2) value property of an object returned by createElement.

https50.ocx in IP*Works! SSL in the server in Unitronics UniOPC before 2.0.0 does not properly implement an unspecified function, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site.

php: safe_mode / open_basedir security fixes in 5.2.13/5.3.2

The safe_mode implementation in PHP before 5.2.13 does not properly handle directory pathnames that lack a trailing / (slash) character, which allows context-dependent attackers to bypass intended access restrictions via vectors related to use of the tempnam function.

The GENESIS32 IcoSetServer ActiveX control in ICONICS GENESIS32 9.21 and BizViz 9.21 configures the trusted zone on the basis of user input, which allows remote attackers to execute arbitrary code via a crafted web site, related to a "Workbench32/WebHMI component SetTrustedZone Policy vulnerability."

Safari on Apple iPhone OS 3.1.3 for iPod touch allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors involving document.write calls with long crafted strings.

Heap-based buffer overflow in the FlashPix PlugIn before 4.3.4.0 for IrfanView might allow remote attackers to execute arbitrary code via a .fpx file containing a crafted FlashPix image that is not properly handled during decompression.

Buffer overflow in the embedded web server on the Siemens Scalance X Industrial Ethernet switch X414-3E before 3.7.1, X308-2M before 3.7.2, X-300EEC before 3.7.2, XR-300 before 3.7.2, and X-300 before 3.7.2 allows remote attackers to cause a denial of service (device reboot) or possibly execute arbitrary code via a malformed URL.

python-qpid: client does not validate qpid server TLS/SSL certificate

The Python client in Apache Qpid before 2.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Use-after-free vulnerability in Google Chrome 17.0.963.66 and earlier allows remote attackers to bypass the DEP and ASLR protection mechanisms, and execute arbitrary code, via unspecified vectors, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012. NOTE: the primary affected product may be clarified later; it was not identified by the researcher, who reportedly stated "it really doesn't matter if it's third-party code."
