Title
OpenSC < 0.27.0 Buffer Overrun in do_key_value() via profile.c
Summary
OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.

Title
OpenSC: `sc_compacttlv_find_tag` can return out-of-bounds pointers
Summary
OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sc_compacttlv_find_tag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag (high nibble) and value length (low nibble). With a 1-byte buffer {0x0A}, the encoded element claims tag=0 and length=10 but no value bytes follow. Calling sc_compacttlv_find_tag with search tag 0x00 returns a pointer equal to buf+1 and outlen=10 without verifying that the claimed value length fits within the remaining buffer. In cases where the sc_compacttlv_find_tag is provided untrusted data (such as being read from cards/files), attackers may be able to influence it to return out-of-bounds pointers leading to downstream memory corruption when subsequent code tries to dereference the pointer. This issue has been patched in version 0.27.0.

Title
OpenSC: Out of Bounds vulnerability
Summary
OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, feeding a crafted input to the fuzz_pkcs15_reader harness causes OpenSC to perform an out-of-bounds heap read in the X.509/SPKI handling path. Specifically, sc_pkcs15_pubkey_from_spki_fields() allocates a zero-length buffer and then reads one byte past the end of that allocation. This issue has been patched in version 0.27.0.

Title
Libopensc: uninitialized values after incorrect check or usage of apdu response values in libopensc
Summary
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.
The following problems were caused by insufficient control of the response APDU buffer and its length when communicating with the card.

Title
Opensc: memory use after free in authentic driver when updating token info
Summary
The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An attacker must have physical access to the computer system and requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can allow for compromised card management operations during enrolment.

This manipulation can allow for compromised card management operations during enrolment."

Title
OpenSC < 0.27.0 Buffer Overrun in do_key_value() via profile.c
Summary
OpenSC before 0.27.0, fixed in commit 0358817, contains a stack and heap buffer overrun vulnerability in the do_key_value() function in src/pkcs15init/profile.c that allows attackers to corrupt memory by supplying a crafted profile configuration file. During pkcs15-init invocation, a key value entry beginning with '=' followed by more than sizeof(keybuf) characters is copied into keybuf via memcpy without a length check, causing both stack and heap buffer overruns.

OpenSC before 0.27.0-rc1, fixed in commit 3f24f0b, contains a stack buffer overflow vulnerability in piv_process_history() in src/libopensc/card-piv.c that allows physically present attackers to trigger memory corruption by presenting a crafted PIV smart card or USB device returning a URL field longer than 118 bytes in the Key History Object ASN.1 response.

Title
OpenSC: `sc_compacttlv_find_tag` can return out-of-bounds pointers
Summary
OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sc_compacttlv_find_tag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag (high nibble) and value length (low nibble). With a 1-byte buffer {0x0A}, the encoded element claims tag=0 and length=10 but no value bytes follow. Calling sc_compacttlv_find_tag with search tag 0x00 returns a pointer equal to buf+1 and outlen=10 without verifying that the claimed value length fits within the remaining buffer. In cases where the sc_compacttlv_find_tag is provided untrusted data (such as being read from cards/files), attackers may be able to influence it to return out-of-bounds pointers leading to downstream memory corruption when subsequent code tries to dereference the pointer. This issue has been patched in version 0.27.0.

OpenSC: Out of Bounds vulnerability
Summary
OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, feeding a crafted input to the fuzz_pkcs15_reader harness causes OpenSC to perform an out-of-bounds heap read in the X.509/SPKI handling path. Specifically, sc_pkcs15_pubkey_from_spki_fields() allocates a zero-length buffer and then reads one byte past the end of that allocation. This issue has been patched in version 0.27.0.

Libopensc: heap buffer overflow in openpgp driver when generating key
Summary
A heap-based buffer overflow vulnerability was found in the libopensc OpenPGP driver. A crafted USB device or smart card with malicious responses to the APDUs during the card enrollment process using the `pkcs15-init` tool may lead to out-of-bound rights, possibly resulting in arbitrary code execution.

Title
Libopensc: uninitialized values after incorrect or missing checking return values of functions in pkcs15init
Summary
A vulnerability was found in pkcs15-init in OpenSC. 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.

CVE-2024-1454 (GCVE-0-2024-1454)
Vulnerability from cvelistv5 – Published: 2024-02-12 22:29 – Updated: 2025-11-07 00:20
VLAI
Title
Opensc: memory use after free in authentic driver when updating token info
Summary
The use-after-free vulnerability was found in the AuthentIC driver in OpenSC packages, occuring in the card enrolment process using pkcs15-init when a user or administrator enrols or modifies cards. An attacker must have physical access to the computer system and requires a crafted USB device or smart card to present the system with specially crafted responses to the APDUs, which are considered high complexity and low severity. This manipulation can allow for compromised card management operations during enrolment.
