QID 670857: EulerOS Security Update for opensc (EulerOS-SA-2021-1158)

OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitate their use in security applications such as authentication, mail encryption and digital signatures. OpenSC implements the PKCS#11 API so applications supporting this API (such as Mozilla Firefox and Thunderbird) can use it. On the card OpenSC implements the PKCS#15 standard and aims to be compatible with every software/card that does so, too. Security Fix(es): The Oberthur smart card software driver in OpenSC before 0.21.0-rc1 has a heap-based buffer overflow in sc_oberthur_read_file.(CVE-2020-26570) The gemsafe GPK smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init.(CVE-2020-26571) The TCOS smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in tcos_decipher.(CVE-2020-26572)
