Red Hat Security Advisory: libgcrypt security and bug fix update

Notes

Topic
An update for libgcrypt 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 libgcrypt library provides general-purpose implementations of various cryptographic algorithms. Security Fix(es): * libgcrypt: mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm (CVE-2021-33560) 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.5 Release Notes linked from the References section.
