Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Missing initialization of resource (CVE-ID: CVE-2024-45615)

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to missing initialization in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


2) Use of uninitialized resource (CVE-ID: CVE-2024-45616)

The vulnerability allows an attacker to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


3) Use of uninitialized resource (CVE-ID: CVE-2024-45617)

The vulnerability allows an attacker to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


4) Use of uninitialized resource (CVE-ID: CVE-2024-45618)

The vulnerability allows an attacker to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources in pkcs15-init in OpenSC. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


5) Use of uninitialized resource (CVE-ID: CVE-2024-45619)

The vulnerability allows an attacker to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources in OpenSC, OpenSC tools, PKCS#11 module, minidriver, and CTK. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


6) Buffer overflow (CVE-ID: CVE-2024-45620)

The vulnerability allows an attacker to bypass implemented security restrictions.

The vulnerability exists due to a boundary error in the pkcs15-init tool in OpenSC. An attacker with physical access to the system can use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.


7) Heap-based buffer overflow (CVE-ID: CVE-2024-8443)

The vulnerability allows an attacker to bypass implemented security restrictions.

The vulnerability exists due to a boundary error in the libopensc OpenPGP driver. An attacker with physical access to the system can use a crafted USB device or smart card with malicious responses to the APDUs during the card enrollment process using the pkcs15-init tool to trigger an out-of-bound rights, possibly resulting in arbitrary code execution.
