A vulnerability was found in OpenSC. This security flaw cause a buffer
overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The
attacker can supply a smart card package with malformed ASN1 context.
The cardos_have_verifyrc_package function scans the ASN1 buffer for 2
tags, where remaining length is wrongly caculated due to moved starting
pointer. This leads to possible heap-based buffer oob read. In cases
where ASAN is enabled while compiling this causes a crash. Further info
leak or more damage is possible.
