A remote code execution vulnerability in OpenText Brava! Desktop 16.6.3.84 due to an out-of-bounds write in DWF file parsing, requiring user interaction.
Vulnerability
This vulnerability affects OpenText Brava! Desktop version 16.6.3.84. The flaw exists in the parsing of DWF files, where the application fails to properly validate user-supplied data, leading to a write past the end of an allocated buffer [1].
Exploitation
An attacker must convince a user to visit a malicious webpage or open a specially crafted DWF file. No authentication is required, and the attack is local in the sense that the user must interact with the malicious content [1].
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This can lead to full compromise of confidentiality, integrity, and availability of the affected system [1].
Mitigation
No fix or workaround is disclosed in the available reference. Users should exercise caution when opening DWF files from untrusted sources [1].
