Name of the Vulnerable Software and Affected Versions Foxit Reader version 9.0.0.29935

Description This issue allows remote attackers to execute arbitrary code on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of BMP images due to the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this to execute code under the context of the current process.

Recommendations For Foxit Reader version 9.0.0.29935, consider disabling the BMP image parsing functionality until a patch is available. Restrict access to potentially malicious files or web pages to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
