CVE-2021-31501

Information disclosure via DWG out-of-bounds read

Published Jun 15, 2021 · Updated Aug 3, 2024

Out-of-bounds read in OpenText Brava! Desktop 16.6.3.84 allows remote attackers to disclose sensitive information through a DWG file. The DWG parser fails to validate user-supplied data before reading beyond the end of an allocated data structure. Exploitation requires the target to visit a malicious page or open a malicious file; the disclosed data can support a separate code-execution chain.
