Multiple integer overflows in Media Player Classic (MPC) 6.4.9.0 and earlier, as used standalone and in mympc (aka CD-Storm) 1.0.0.1, StormPlayer 1.0.4, and possibly other products, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values.

Media Player Classic (MPC) allows user-assisted remote attackers to cause a denial of service (application crash) via a malformed .au file that triggers a divide-by-zero error.

Buffer overflow in the CFLICStream::_deltachunk function in FLICSource.cpp in Media Player Classic (MPC) 6.4.9.0 allows user-assisted remote attackers to execute arbitrary code via a crafted FLI file.

Cross-site scripting (XSS) vulnerability in index.php in the WordPress Classic 1.5 theme in WordPress before 2.1.3 allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO (PHP_SELF).

Media Player Classic (MPC) 6.4.9.0 allows user-assisted remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted FLV file.

Divide-by-zero error in Media Player Classic (MPC) 6.4.9.0 allows user-assisted remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted MPA file.

Media Player Classic 6.4.9.0 allows user-assisted remote attackers to cause a denial of service (web browser crash) via an "empty" .MPA file, which triggers a divide-by-zero error.

MySource Matrix 3.8 and earlier, and MySource 2.x, allow remote attackers to use the application as an HTTP proxy server via the sq_remote_page_url parameter to access arbitrary sites with the server's IP address and conduct cross-site scripting (XSS) attacks. NOTE: the researcher reports that "The vendor does not consider this a vulnerability.

Unspecified vulnerability in MySource Classic 2.14.6, and possibly earlier, allows remote authenticated users, with superuser privileges, to inject arbitrary PHP code via unspecified vectors related to the Equation attribute in Web_Extensions - Notitia (I/II). NOTE: due to lack of details, it is not clear whether this issue is file inclusion, static code injection, or another type of issue.
