ID CVE-2010-0421
Summary Array index error in the hb_ot_layout_build_glyph_classes function in pango/opentype/hb-ot-layout.cc in Pango before 1.27.1 allows context-dependent attackers to cause a denial of service (application crash) via a crafted font file, related to building a synthetic Glyph Definition (aka GDEF) table by using this font's charmap and the Unicode property database.

CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description From Red Hat Security Advisory 2010:0140 : Updated pango and evolution28-pango packages that fix one security issue are now available for Red Hat Enterprise Linux 3, 4, and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. Pango is a library used for the layout and rendering of internationalized text. An input sanitization flaw, leading to an array index error, was found in the way the Pango font rendering library synthesized the Glyph Definition (GDEF) table from a font's character map and the Unicode property database. If an attacker created a specially crafted font file and tricked a local, unsuspecting user into loading the font file in an application that uses the Pango font rendering library, it could cause that application to crash. (CVE-2010-0421) Users of pango and evolution28-pango are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, you must restart your system or restart your X session for this update to take effect.

    description Marc Schoenefeld discovered that Pango incorrectly handled certain Glyph Definition (GDEF) tables. If a user were tricked into displaying text with a specially crafted font, an attacker could cause Pango to crash, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS and 9.10. (CVE-2010-0421) Dan Rosenberg discovered that Pango incorrectly handled certain FT_Bitmap objects. If a user were tricked into displaying text with a specially- crafted font, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2011-0020) It was discovered that Pango incorrectly handled certain memory reallocation failures. If a user were tricked into displaying text in a way that would cause a reallocation failure, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10. (CVE-2011-0064). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
