Summary
Red Hat Security Advisory: libyang security update

Notes

Topic
An update for libyang is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. 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 libyang package provides a library for YANG data modeling language. libyang is a YANG data modelling language parser and toolkit written (and providing API) in C. The library is used e.g. in libnetconf2, Netopeer2, sysrepo and FRRouting projects. Security Fix(es): * libyang: stack-based buffer overflow in make_canonical when bits leaf type is used (CVE-2019-19333) * libyang: stack-based buffer overflow in make_canonical when identityref leaf type is used (CVE-2019-19334) 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. IMPORTANT: The libyang-devel sub-package has recently been removed from the AppStream repository. If you have previously installed libyang-devel, remove it prior to applying this advisory to make the update successful.
