The Embedded OpenType (EOT) Font Engine (T2EMBED.DLL) in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP2, Vista Gold, SP1, and SP2, and Server 2008 Gold and SP2 allows remote attackers to execute arbitrary code via a crafted name table in a data record that triggers an integer truncation and a heap-based buffer overflow, aka Embedded OpenType Font Heap Overflow Vulnerability.
Weakness
When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
