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)
