Microsoft Security Bulletin MS15-021 - Critical

Vulnerabilities in Adobe Font Driver Could Allow Remote Code Execution (3032323)

Published: March 10, 2015

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted file or website. An attacker who successfully exploited the vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software section.

The security update addresses the vulnerability by correcting how the font parser allocates memory and by correcting how objects in memory are handled. For more information about the vulnerability, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 3032323.

Vulnerability Information

Adobe Font Driver Denial of Service Vulnerability - CVE-2015-0074

A denial of service vulnerability exists in how the Adobe Font Driver manages memory when parsing fonts. A user who visited a specially crafted website or opened a specially crafted file could be affected by this vulnerability. The update addresses this vulnerability by correcting how the font parser allocates memory.

Microsoft received information about this vulnerability through coordinated vulnerability disclosure. When this security bulletin was issued, Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.

Mitigating Factors

Microsoft has not identified any mitigating factors for this vulnerability.

Workarounds

Microsoft has not identified any workarounds for this vulnerability.

Multiple Adobe Font Driver Information Disclosure Vulnerabilities

Information disclosure vulnerabilities exist in the Adobe Font Driver that could allow the disclosure of memory contents to an attacker. These vulnerabilities are caused when the Adobe Font Driver tries to read or display certain fonts. An attacker could use the vulnerabilities to gain information about the system that could then be combined with other attacks to compromise the system. The information disclosure vulnerabilities by themselves do not allow arbitrary code execution. However, an attacker could use these vulnerabilities in conjunction with another vulnerability to bypass security features such as Kernel Address Space Layout Randomization (KASLR). The update addresses the vulnerabilities by correcting how objects in memory are handled.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability title CVE number Publicly Disclosed Exploited
Adobe Font Driver Information Disclosure Vulnerability CVE-2015-0087 No No
Adobe Font Driver Information Disclosure Vulnerability CVE-2015-0089 No No

Mitigating Factors

Microsoft has not identified any mitigating factors for this vulnerability.

Workarounds

Microsoft has not identified any workarounds for this vulnerability.

Multiple Adobe Font Driver Remote Code Execution Vulnerabilities

Vulnerabilities exist in the Adobe Font Driver that could allow remote code execution if a user views a specially crafted file or website. The vulnerabilities are caused when the Adobe Font Driver improperly overwrites objects in memory. The vulnerabilities could allow an attacker to run code in kernel-mode and then install programs; view, change, or delete data; or create new accounts with full administrative rights. The update addresses these vulnerabilities by correcting how the Adobe Font Driver handles objects in memory.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability title CVE number Publicly Disclosed Exploited
Adobe Font Driver Remote Code Execution Vulnerability CVE-2015-0088 No No
Adobe Font Driver Remote Code Execution Vulnerability CVE-2015-0090 No No
Adobe Font Driver Remote Code Execution Vulnerability CVE-2015-0091 No No
Adobe Font Driver Remote Code Execution Vulnerability CVE-2015-0092 No No
Adobe Font Driver Remote Code Execution Vulnerability CVE-2015-0093 No No

Mitigating Factors

Microsoft has not identified any mitigating factors for this vulnerability.

Workarounds

The following workarounds may be helpful in your situation:

  • In a web-based attack scenario, an attacker could host a website that contains a web page that is used to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these websites. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an instant messenger or email message that takes users to the attacker's website.
  • By default, all supported versions of Microsoft Outlook, Microsoft Outlook Express, and Windows Mail open HTML email messages in the Restricted sites zone, which disables font download by default. If a user clicks a link in an email message, the user could still be vulnerable to exploitation of this vulnerability through the web-based attack scenario. The vulnerability could also be exploited if a user opens an attachment that is sent in an email message.
