Summary
Red Hat Security Advisory: flac security update

Notes

Topic
An update for flac is now available for Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.2 Telecommunications Update Service, and Red Hat Enterprise Linux 8.2 Update Services for SAP Solutions. 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
FLAC stands for Free Lossless Audio Codec. FLAC is similar to Ogg Vorbis, but lossless. The FLAC project consists of the stream format, reference encoders and decoders in library form, a command-line program to encode and decode FLAC files, and a command-line metadata editor for FLAC files. Security Fix(es): * flac: Remote Code Execution (RCE) via the bitwriter_grow_ function, by supplying crafted input to the encoder (CVE-2020-22219) 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.
