Use-after-free vulnerability in pcsc-lite before 1.8.20 allows a remote attackers to cause denial of service (crash) via a command that uses cardsList after the handle has been released through the SCardReleaseContext function.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
