TITLE

Apple Mac OS X Run on Safari Vulnerable to arbitrary code execution

DESCRIPTION

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. 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. Apple Safari is a web browser software. -- Vendor Response: Apple has issued an update to correct this vulnerability.
