Summary

Adobe Font Driver in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows remote attackers to execute arbitrary code via a crafted (1) web site or (2) file, aka "Adobe Font Driver Remote Code Execution Vulnerability," a different vulnerability than CVE-2015-0088, CVE-2015-0090, CVE-2015-0092, and CVE-2015-0093.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating User-Controlled Variables
    This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

descriptionThe remote Windows host is affected by the following vulnerabilities in the Adobe Font driver : - A flaw exists in the Adobe Font Driver due to improper allocation of memory. This allows a remote attacker, using a specially crafted font in a file or website, to cause a denial of service. (CVE-2015-0074) - Multiple flaws exist in the Adobe Font Driver that allow a remote attacker, using specially crafted fonts, to obtain sensitive information from kernel memory. (CVE-2015-0087, CVE-2015-0089) - Multiple flaws exist in the Adobe Font Driver due to improper validation of user-supplied input. A remote attacker can exploit this, using a specially crafted font in a file or website, to execute arbitrary code. (CVE-2015-0088, CVE-2015-0090, CVE-2015-0091, CVE-2015-0092, CVE-2015-0093)
