CVE-2010-1883

Desbordamiento de entero en el Embedded OpenType (EOT) Font Engine en Microsoft Windows XP SP2 y SP3, Windows Server 2003 SP2, Windows Vista SP1 y SP2, Windows Server 2008 Gold, SP2, y R2, y Windows 7 permite a los atacantes remotos ejecutar códio a su elección a través de una tabla manipulada en una fuente embebida, también conocido como "Embedded OpenType Font Integer Overflow Vulnerability".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the conversion of an Embedded OpenType file to TrueType format within t2embed.dll. The most likely vector for this to be exploited is via Internet Explorer as an embedded font in an HTML/CSS document. The flaw itself is due to an integer overflow when parsing hdmx records. A record size and record count variable are trusted and operated upon. The resulting value is used in a copy loop that can be manipulated to corrupt memory. This can be abused by an attacker to execute remote code under the context of the user running the browser.
