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

Description This issue allows remote attackers to execute arbitrary code 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 DWF files due to the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this to execute code in the context of the current process.

Recommendations For OpenText Brava! Desktop version 16.6.3.84, consider disabling the DWF file parsing functionality until a patch is available to prevent exploitation. Restrict access to untrusted files and websites to minimize the risk of remote code execution. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
