Description

This security bulletin contains information about 7 vulnerabilities.


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

CWE-ID: CWE-909 - Missing initialization of resource

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


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.
