| CVE-2021-34193 | Hig | 0.49 | 7.5 | 0.01 | Aug 22, 2023 | Stack overflow vulnerability in OpenSC smart card middleware before 0.23 via crafted responses to APDUs. | ||
| CVE-2019-16058 | Hig | 0.49 | 7.5 | 0.02 | Sep 6, 2019 | An issue was discovered in the pam_p11 component 0.2.0 and 0.3.0 for OpenSC. If a smart card creates a signature with a length longer than 256 bytes, this triggers a buffer overflow. This may be the case for RSA keys with 4096 bits depending on the signature scheme. | ||
| CVE-2019-6502 | Hig | 0.49 | 7.5 | 0.02 | Jan 22, 2019 | sc_context_create in ctx.c in libopensc in OpenSC 0.19.0 has a memory leak, as demonstrated by a call from eidenv. | ||
