Black Hat USA 2014: Breaking Windows

In our last Intel update before the imminent show (are you hyped? we are!) we're checking out three Briefings that center on vulnerabilities in Microsoft Windows. No kidding, Windows has vulnerabilities! Let's see what's what.

Microsoft's Font Scaler engine is widely used in Windows and Mac OS for rendering TrueType/OpenType fonts. To improve performance Microsoft moved it from user mode to kernel mode. Unfortunately this means Font Scaler represents a significant kernel attack surface, perhaps the easiest point which can be reached remotely (remember 2011's Duqu malware?). Understanding TOCTTOU in the Windows Kernel Font Scaler Engine will take you on a tour of the Font Scaler's many vulnerabilities, with the Time-of-Check to Time-of-Use (TOCTTOU) type being most critical.

Ever wondered about the attack surface of Windows graphics drivers? Are they similar to other drivers? Do they expose input/output controls? In the aptly titled Windows Kernel Graphics Driver Attack Surface those questions and more will be answered by low-level kernel expert Ilja van Sprundel. Whether you're a security researcher, a developer looking for some security guidance when writing drivers, or just generally curious about driver internals, there's something here for everyone.

In June 2013, Microsoft started the first of their new bug-bounty programs, focusing on finding vulnerabilities in IE11 on the upcoming Windows 8.1. Instead of fuzzing for RCEs, James Forshaw sought out logic bugs in IE11's sandbox implementation... and it wasn't nearly as tough as he expected. Digging for IE11 Sandbox Escapes will take you on a deep dive into the four unique sandbox escapes he discovered throughout June, some of which go all the way back to IE7 and Vista. Come learn how to investigate the IE11 sandbox and test the issues out yourself.

Regular registration ended on July 26, which was a couple days ago. Late registration is still available, though, so get over to Black Hat USA 2014's registration page if you want to come join the party.

CVE-2013-6501
Published: 2015-03-30
The default soap.wsdl_cache_dir setting in (1) php.ini-production and (2) php.ini-development in PHP through 5.6.7 specifies the /tmp directory, which makes it easier for local users to conduct WSDL injection attacks by creating a file under /tmp with a predictable filename that is used by the get_s...

CVE-2014-9652
Published: 2015-03-30
The mconvert function in softmagic.c in file before 5.21, as used in the Fileinfo component in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5, does not properly handle a certain string-length field during a copy of a truncated version of a Pascal string, which might allow remote atta...

CVE-2014-9653
Published: 2015-03-30
readelf.c in file before 5.22, as used in the Fileinfo component in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5, does not consider that pread calls sometimes read only a subset of the available data, which allows remote attackers to cause a denial of service (uninitialized memory ...

CVE-2014-9705
Published: 2015-03-30
Heap-based buffer overflow in the enchant_broker_request_dict function in ext/enchant/enchant.c in PHP before 5.4.38, 5.5.x before 5.5.22, and 5.6.x before 5.6.6 allows remote attackers to execute arbitrary code via vectors that trigger creation of multiple dictionaries.

CVE-2014-9709
Published: 2015-03-30
The GetCode_ function in gd_gif_in.c in GD 2.1.1 and earlier, as used in PHP before 5.5.21 and 5.6.x before 5.6.5, allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted GIF image that is improperly handled by the gdImageCreateFromGif function.
