1. Summary:

An update for yum 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

Yum is a command-line utility that allows the user to check for updates and automatically download and install updated RPM packages. Yum automatically obtains and downloads dependencies, prompting the user for permission as necessary.

The following packages have been upgraded to a later upstream version: dnf (4.2.7), dnf-plugins-core (4.0.8), libcomps (0.1.11), libdnf (0.35.1), librepo (1.10.3), libsolv (0.7.4). (BZ#1690288, BZ#1690289, BZ#1690299, BZ#1692402, BZ#1694019, BZ#1697946)

Security Fix(es):

* libcomps: use after free when merging two objmrtrees (CVE-2019-3817)
* libsolv: illegal address access in pool_whatprovides in src/pool.h (CVE-2018-20534)

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.
