Application denial-of-service via NULL pointer dereference
Published Oct 14, 2022 · Updated Apr 23, 2025
NULL pointer dereference in Adobe Acrobat Reader 22.002.20212 and earlier allows attackers to crash the application via a malicious file. Adobe has not disclosed the affected parser or the operation that supplies a null pointer for dereference.
