Sensitive information disclosure via DWF out-of-bounds read
Published Jun 15, 2021 · Updated Aug 3, 2024
An out-of-bounds read in OpenText Brava! Desktop 16.6.3.84 allows remote attackers to disclose sensitive information via malicious DWF files. The DWF parser fails to validate attacker-supplied data before reading beyond an allocated structure, exposing process memory. Exploitation requires a victim to visit a malicious page or open the crafted file; the disclosed data impact is confidentiality, while code execution requires chaining other flaws.
