Synopsis:          Moderate: brotli security update
Advisory ID:       RHSA-2021:1702-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2021:1702
Issue date:        2021-05-18
CVE Names:         CVE-2020-8927 
=====================================================================

1. Summary:

An update for brotli 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, ppc64le, s390x, x86_64

3. Description:

Brotli is a generic-purpose lossless compression algorithm that compresses
data using a combination of a modern variant of the LZ77 algorithm, Huffman
coding and 2nd order context modeling, with a compression ratio comparable
to the best currently available general-purpose compression methods. It is
similar in speed with deflate but offers more dense compression. 

Security Fix(es):

* brotli: buffer overflow when input chunk is larger than 2GiB
(CVE-2020-8927)
