Red Hat Security Advisory: fribidi security update

Notes

Topic
An update for fribidi 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
FriBidi is a library to handle bidirectional scripts (for example Hebrew, Arabic), so that the display is done in the proper way, while the text data itself is always written in logical order. Security Fix(es): * fribidi: Stack based buffer overflow (CVE-2022-25308) * fribidi: Heap-buffer-overflow in fribidi_cap_rtl_to_unicode (CVE-2022-25309) * fribidi: SEGV in fribidi_remove_bidi_marks (CVE-2022-25310) 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 8.7 Release Notes linked from the References section.
