Name of the Vulnerable Software and Affected Versions OpenText Brava! Desktop version 16.6.3.84

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 DWG files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated data structure. An attacker can leverage this, in conjunction with other issues, to execute arbitrary code in the context of the current process.

Recommendations For OpenText Brava! Desktop version 16.6.3.84, consider disabling the DWG file parsing functionality until a patch is available to prevent exploitation. Restrict access to malicious pages or files to minimize the risk of sensitive information disclosure. At the moment, there is no information about a newer version that contains a fix for this issue.
