Name of the Vulnerable Software and Affected Versions Bentley View version 10.15.0.75

Description This issue allows remote attackers to disclose sensitive information on affected 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 user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this, in conjunction with other issues, to execute arbitrary code in the context of the current process.

Recommendations For version 10.15.0.75, 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. Avoid using user-supplied data in the BMP image parsing process until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this issue.
