Name of the Vulnerable Software and Affected Versions OpenText Brava! Desktop version 16.6.4.55

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 PDF files due to the lack of proper validation of user-supplied data. This can result in a read past the end of an allocated data structure, potentially allowing an attacker to execute arbitrary code in the context of the current process when combined with other vulnerabilities.

Recommendations For OpenText Brava! Desktop version 16.6.4.55, consider disabling the PDF 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.
