CVE-2024-45616: Uninitialized values after incorrect check or usage of APDU response values in libopensc

The following problems were caused by insufficient control of the response APDU buffer and its length when communicating with the card. The uninitialized variables were reflected in these functions:

Affected versions: all before 0.26.0
