Descriptions

Multiple stack-based buffer overflows in CoolType.dll in Adobe Reader and Acrobat 8.x before 8.3.1, 9.x before 9.4.6, and 10.x before 10.1.1 allow attackers to execute arbitrary code via unspecified vectors.

Múltiples desbordamientos de búfer basados en pila en CoolType.dll in Adobe Reader y Acrobat v8.x antes de v8.3.1, v9.x antes de v9.4.6, y v10.x antes de v10.1.1, permite a atacantes remotos ejecutar código de su elección a través de vectores no especificados.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader. 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 way Adobe Reader handles compound glyphs. When a glyph has more then 0x7FFF 'numberOfContours' a sign extension occurs resulting in a buffer under-read. Simple glyphs are checked when Adobe Reader parses the font info, but the value for 'numberOfContours' in an compound glyph is the sum of all its child glyphs, and this is not checked. This could result in remote code execution under the context of the current user.
