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.
