Name of the Vulnerable Software and Affected Versions Bitdefender Engines versions prior to 7.76662

Description A lack of proper validation of user-supplied data in the iso.xmd parser can result in a division-by-zero circumstance. This issue can be exploited to cause a denial-of-service when paired with other vulnerabilities. User interaction is required, where the target must visit a malicious page or open a malicious file.

Recommendations For versions prior to 7.76662, update to version 7.76662 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially malicious pages or files to minimize the risk of exploitation.
