Opensc Project: >> Opensc >> 0.23.0 Security Vulnerabilities
Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow
compromise key generation, certificate loading, and other card management operations during enrollment.

A vulnerbility 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.
