opensc-0.20.0-2.el8

The OpenSC set of libraries and utilities provides support for working with smart cards. OpenSC focuses on cards that support cryptographic operations and enables their use for authentication, mail encryption, or digital signatures.

The following packages have been upgraded to a later upstream version: opensc (0.20.0).

Security Fix(es):

* opensc: Out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c (CVE-2019-15945)

* opensc: Out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c (CVE-2019-15946)

* opensc: Improper handling of buffer limits for CAC certificates (CVE-2019-19481)

* opensc: Double free in coolkey_free_private_data in libopensc/card-coolkey.c (CVE-2019-20792)

* opensc: Incorrect read operation during parsing of a SETCOS file attribute (CVE-2019-19479)

Additional Changes:

CVE-2019-15945
OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c.
CVE-2019-15946
OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c.
CVE-2019-19479
An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-setcos.c has an incorrect read operation during parsing of a SETCOS file attribute.
CVE-2019-19481
An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-cac1.c mishandles buffer limits for CAC certificates.
CVE-2019-20792
OpenSC before 0.20.0 has a double free in coolkey_free_private_data because coolkey_add_object in libopensc/card-coolkey.c lacks a uniqueness check.
