CVE-2024-45617

A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs.

Insufficient or missing checking of return values of functions leads to unexpected work with variables that have not been initialized.

An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. Insufficient or missing checking of return values of functions leads to unexpected work with variables that have not been initialized.

OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitate their use in security applications such as authentication, mail encryption and digital signatures. OpenSC implements the standard APIs to smart cards, e.g. PKCS#11 API, Windows’ Smart Card Minidriver and macOS Tokend.

Security Fix(es):

A vulnerability was found in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. The problem is missing initialization of variables expected to be initialized (as arguments to other functions, etc.).(CVE-2024-45615)
