Summary
opensc vulnerabilities
Details
It was discovered that some OpenSC smart card drivers mishandled memory when performing certain decoding operations. An attacker could possibly use this issue to cause a denial of service or other unspecified impact. This issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 ESM. (CVE-2019-15945, CVE-2019-15946)
It was discovered that some OpenSC smart card drivers had buffer overflow vulnerabilities. An attacker could possibly use this issue to cause a denial of service or other unspecified impact. (CVE-2020-26570, CVE-2020-26571, CVE-2020-26572)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
