| CVE-2009-1603 | Hig | 0.49 | 7.5 | 0.01 | | May 11, 2009 | src/tools/pkcs11-tool.c in pkcs11-tool in OpenSC 0.11.7, when used with unspecified third-party PKCS#11 modules, generates RSA keys with incorrect public exponents, which allows attackers to read the cleartext form of messages that were intended to be encrypted. |
| CVE-2025-13763 | Med | 0.37 | 5.7 | 0.00 | | Apr 23, 2026 | Multiple uses of uninitialized variables were found in libopensc that may lead to information disclosure or application crash. An attack requires a crafted USB device or smart card that would present the system with specially crafted responses to the APDUs |
| CVE-2025-66215 | Low | 0.25 | 3.8 | 0.00 | | Mar 30, 2026 | OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, an attacker with physical access to the computer at the time user or administrator uses a token can cause a stack-buffer-overflow WRITE in card-oberthur. The attack requires crafted USB device or smart card that would present the system with specially crafted responses to the APDUs. This issue has been patched in version 0.27.0. |
| CVE-2025-66038 | Low | 0.25 | 3.9 | 0.00 | | Mar 30, 2026 | 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. |
| CVE-2025-66037 | Low | 0.25 | 3.9 | 0.00 | | Mar 30, 2026 | 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. |
| CVE-2025-49010 | Low | 0.18 | 3.8 | 0.00 | | Mar 30, 2026 | OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, an attacker with physical access to the computer at the time user or administrator uses a token can cause a stack-buffer-overflow write in GET RESPONSE. The attack requires crafted USB device or smart card that would present the system with specially crafted responses to the APDUs. This issue has been patched in version 0.27.0. |
| CVE-2009-0368 | | 0.03 | — | 0.00 | | Mar 2, 2009 | OpenSC before 0.11.7 allows physically proximate attackers to bypass intended PIN requirements and read private data objects via a (1) low level APDU command or (2) debugging tool, as demonstrated by reading the 4601 or 4701 file with the opensc-explorer or opensc-tool program. |
| CVE-2010-4523 | | 0.00 | — | 0.00 | | Jan 7, 2011 | Multiple stack-based buffer overflows in libopensc in OpenSC 0.11.13 and earlier allow physically proximate attackers to execute arbitrary code via a long serial-number field on a smart card, related to (1) card-acos5.c, (2) card-atrust-acos.c, and (3) card-starcos.c. |
| CVE-2008-3972 | | 0.00 | — | 0.00 | | Sep 11, 2008 | pkcs15-tool in OpenSC before 0.11.6 does not apply security updates to a smart card unless the card's label matches the "OpenSC" string, which might allow physically proximate attackers to exploit vulnerabilities that the card owner expected were patched, as demonstrated by exploitation of CVE-2008-2235. |
| CVE-2008-2235 | | 0.00 | — | 0.00 | | Aug 1, 2008 | OpenSC before 0.11.5 uses weak permissions (ADMIN file control information of 00) for the 5015 directory on smart cards and USB crypto tokens running Siemens CardOS M4, which allows physically proximate attackers to change the PIN. |
