Adobe Acrobat and Reader versions 2020.006.20042 and earlier, 2017.011.30166 and earlier, 2017.011.30166 and earlier, and 2015.006.30518 and earlier have an use-after-free vulnerability. Successful exploitation could lead to arbitrary code execution .
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
