CVE-2020-15305Public exploit

Application crash via missing error-path throw

Published Jun 26, 2020 · Updated Aug 4, 2024

Use-after-free in OpenEXR before 2.5.2 allows local users to crash applications that process a crafted deep-scan-line EXR file. The DeepScanLineInputFile constructor deletes its internal data object after an input-validation exception but, because the error path omits a throw, continues and reads the freed object. Exploitation requires an application to parse the malformed file and is bounded to an application crash; published scoring reports no confidentiality or integrity impact.
