Summary
Red Hat Security Advisory: opensc security, bug fix, and enhancement update
Notes
Topic
An update for opensc is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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.
Security Fix(es):
* opensc: heap-based buffer overflow in sc_oberthur_read_file (CVE-2020-26570)
* opensc: stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init (CVE-2020-26571)
* opensc: stack-based buffer overflow in tcos_decipher (CVE-2020-26572)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Summary
Red Hat Security Advisory: opensc security, bug fix, and enhancement update
Notes
Topic
An update for opensc is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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.
Security Fix(es):
* opensc: heap-based buffer overflow in sc_oberthur_read_file (CVE-2020-26570)
* opensc: stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init (CVE-2020-26571)
* opensc: stack-based buffer overflow in tcos_decipher (CVE-2020-26572)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
