CVE-2011-2111

Status Candidate

Overview

IML32.dll in Adobe Shockwave Player before 11.6.0.626 allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2011-2115 and CVE-2011-2116.

Adobe Shockwave iml32.dll DEMX Chunk GIF Parsing Remote Code Execution
Posted Jun 16, 2011
Authored by Aaron Portnoy, Logan Brown | Site tippingpoint.com

A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Adobe Shockwave Player. 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 DEMX chunk inside Adobe's RIFF-based Director file format. The code within the IML32.dll does not properly parse GIF images. This can lead to memory corruption which can be leveraged to execute arbitrary code under the context of the user running the browser.

A vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Adobe Shockwave Player. 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 CSWV chunk inside Adobe's RIFF-based Director file format. When handling certain substructures, the code does not properly ensure arithmetic operations will not exceed expected values. By crafting a file with certain values this can be abused to cause memory corruption which can be leveraged to execute arbitrary code under the context of the user running the browser.

Zero Day Initiative Advisory 11-212

Zero Day Initiative Advisory 11-212 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Shockwave. 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 Shockwave handles KEY* elements in a Director file. The Shockwave player will allocate memory with a size taken from the Shockwave file but will always copy a few bytes into that allocation. KEY* sizes smaller then 4 will therefore cause an overwrite of the allocation. By cleverly crafting the input file, an attacker can leverage this to execute remote code under the context of the current user.

Zero Day Initiative Advisory 11-206

Zero Day Initiative Advisory 11-206 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Adobe Shockwave Player. 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 support for embedded GIF images inside Adobe's RIFF-based Director file format. The code within the IML32.dll module does not properly check a counter value that is decreased during loop iterations for an integer underflow. By crafting a GIF image with a sufficiently small value this can lead to memory corruption which can be leveraged to execute arbitrary code under the context of the user running the browser.
