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.

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

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

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.
