ZDI-10-191: Adobe Reader ICC Parsing Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-10-191 October 6, 2010 -- CVE ID: CVE-2010-3621 -- CVSS: 9, (AV:N/AC:L/Au:N/C:P/I:P/A:C) -- Affected Vendors: Adobe -- Affected Products: Adobe Reader -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader. User interaction is required in that a target must be coerced into opening a file or visiting a web page. The specific flaw exists within the ACE.dll module responsible for parsing ICC streams. When processing an ICC stream, the process performs math on two DWORD values from the input file. If these values wrap over the maximum integer value of 0xFFFFFFFF a mis-allocation can occur. Later, the process uses one of the original DWORD values as a size to a copy function. This can be abused by an attacker to overflow a stack buffer and subsequently execute code under the context of the user running the process.
Well, awesome. This sounds near-identical to some issues that the Sun JRE had a few years back[1]. I wonder if the code shares a common lineage? :) Cheers Chris [1] - http://scary.beasts.org/security/CESA-2006-004.html http://scary.beasts.org/misc/jdk/badicc.jpg (And additional integer problems not released at the time) http://scary.beasts.org/misc/jdk/badicc2.jpg http://scary.beasts.org/misc/jdk/badicc3.jpg http://scary.beasts.org/misc/jdk/badicc4.jpg http://scary.beasts.org/security/CESA-2007-005.html In addition, there have been plenty of bugs against lcms[2] and Apple's ICC profile parser. So it seems like ICC profile parsing is hard ;-) [2] - http://scary.beasts.org/security/CESA-2009-003.html
