TITLE

Adobe Shockwave Player of pami RIFF chunk Arbitrary code execution vulnerability in parsing

DESCRIPTION

The implementation of pami RIFF chunk parsing in Adobe Shockwave Player before 11.5.7.609 does not validate a certain value from a file before using it in file-pointer calculations, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted .dir (aka Director) file. 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 code responsible for parsing Director files. When the application parses the pami RIFF chunk, it trusts an offset value and seeks into the file data. If provided with signed values in the data at the given offset, the process can be made to incorrectly calculate a pointer and operate on the data at it's location. This can be abused by an attacker to execute arbitrary code under the context of the user running the browser. Adobe Shockwave Player 11.5.6.606 and prior are vulnerable. NOTE: This issue was previously discussed in BID 40066 (Adobe Shockwave Player APSB10-12 Multiple Remote Vulnerabilities) but has been given its own record to better document it. These people now have access to some of the best the Web has to offer - including dazzling 3D games and entertainment, interactive product demonstrations, and online learning applications. The vulnerable software fails to sanitize user input when processing .dir files resulting in a crash and overwrite of a few memory registers.<br/><br/> --------------------------------------------------------------------------------<br/><br/><code> (f94.ae4): Access violation - code c0000005 (first chance)<br/> First chance exceptions are reported before any exception handling.<br/> This exception may be expected and handled.<br/> eax=20a0a0a0 ebx=207d004c ecx=00000400 edx=41414140 esi=00000000 edi=a80487d8<br/> eip=68008bd6 esp=0012de4c ebp=00000400 iopl=0 nv up ei pl nz na pe nc<br/> cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00050206<br/> *** WARNING: Unable to verify checksum for C:\Program Files\Adobe\Adobe Director 11\DIRAPI.dll<br/> *** ERROR: Symbol file could not be found.

Secunia is hiring skilled researchers and talented developers. 1) A boundary error while processing FFFFFF45h Shockwave 3D blocks can be exploited to corrupt memory. 2) A signedness error in the processing of Director files can be exploited to corrupt memory. 3) An array indexing error when processing Director files can be exploited to corrupt memory. 4) An integer overflow error when processing Director files can be exploited to corrupt memory. 5) An error when processing asset entries contained in Director files can be exploited to corrupt memory. 6) A boundary error when processing embedded fonts can be exploited to cause a heap-based buffer overflow via a specially crafted Director file. 7) An error when processing Director files can be exploited to overwrite 4 bytes of memory. 8) An error in the implementation of ordinal function 1409 in iml32.dll can be exploited to corrupt heap memory via a specially crafted Director file. 9) An error when processing a 4-byte field inside FFFFFF49h Shockwave 3D blocks can be exploited to corrupt heap memory. 10) An unspecified error can be exploited to corrupt memory. 11) A second unspecified error can be exploited to corrupt memory. 12) A third unspecified error can be exploited to corrupt memory. 13) A fourth unspecified error can be exploited to cause a buffer overflow. 14) A fifth unspecified error can be exploited to corrupt memory. 15) A sixth unspecified error can be exploited to corrupt memory. 16) A seventh unspecified error can be exploited to corrupt memory. 17) An error when processing signed values encountered while parsing "pami" RIFF chunks can be exploited to corrupt memory. Successful exploitation of the vulnerabilities may allow execution of arbitrary code. The vulnerabilities are reported in versions 11.5.6.606 and prior on Windows and Macintosh.
