Memory disclosure via unchecked CDR bounds
Published Oct 1, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Corel DrawStandard 2020 22.0.0.474 allows unauthenticated attackers to disclose memory via crafted CDR files. The CdrCore.dll decoder performs an improper bounds check while parsing malformed CDR data, causing out-of-bounds memory access. Exploitation requires a victim to open the malicious file; the documented consequence is unauthorized memory disclosure in the current user's context, with no reported integrity or availability impact.
