This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 DIRAPIX.dll which is responsible for parsing the Director movies, a RIFF-based file format. The code sign-extends a value from the input file and uses it as an offset to seek into a heap buffer before performing a write operation. By crafting particular values for this field, an attacker can force the process to seek beyond the allocated bounds of the buffer. This can be leveraged by an attacker to execute arbitrary code under the context of the user running the web browser.
a5b00042c264d908492a78e03e2b000c4d556668645f8023c4c9840bbe65d7afThis vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 DIRAPIX.dll which is responsible for parsing the Director movies, a RIFF-based file format. The code directly uses a value from the file while seeking into a heap buffer. The process then attempts to write a NULL byte to the seeked address. By specifying a large enough value for this field, an attacker can force the process to seek beyond the allocated bounds of the buffer. This can be leveraged by an attacker to execute arbitrary code under the context of the user running the web browser.
434a38f35c1ac47096e5844b388206de10edb7761328457c75b27d8e27b0ba9dThis vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 IML32X.dll and DIRAPIX.dll which are responsible for parsing the Director movies, a RIFF-based file format. The code trusts a value from the file as a count and performs an endian-flipping loop on data in heap memory. If the value is large enough the process can be made to seek outside the bounds of the allocation and thus corrupt memory in a controlled fashion. This can be leveraged by an attacker to execute arbitrary code under the context of the user running the web browser.
