Descriptions

Unspecified vulnerability in Safari 4 on Apple Mac OS X 10.6 allows remote attackers to execute arbitrary code via unknown vectors, as demonstrated by Charlie Miller during a Pwn2Own competition at CanSecWest 2010.

Vulnerabilidad sin especificar en Safari 4 sobre Apple Mac Os X v10.6, permite a atacantes remotos ejecutar código de su elección a través de vectores desconocidos, como ha demostrado Charlie Miller durante la competición Pwn2Own en CanSecWest 2010.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Preview. User interaction is required in that a target must open a malicious file or visit a malicious page.
The specific flaw exists within the routine TType1ParsingContext::SpecialEncoding() defined in libFontParser.dylib. While parsing glyphs from a PDF document, a malformed offset greater than 0x400 can result in a heap corruption which can be leveraged by an attacker to execute arbitrary code under the context of the current user.
