Vulnerability
This vulnerability exists in the BMP file parsing functionality of OpenText Brava! Desktop Build 16.6.4.55. The lack of proper validation of user-supplied data can result in a write past the end of an allocated buffer, leading to memory corruption. Affected versions are limited to Build 16.6.4.55. [1]
Exploitation
An attacker must craft a malicious BMP file and convince the target user to open it or visit a malicious page. User interaction is required, as the target must trigger the parsing of the BMP file. No other privileges or network position are needed beyond delivering the file. [1]
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This can lead to full confidentiality, integrity, and availability compromise of the affected system. [1]
Mitigation
