Red Hat Security Advisory
Synopsis: Moderate: rsync security and bug fix update
Advisory ID: RHSA-2022:8291-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2022:8291
Issue date: 2022-11-15
CVE Names: CVE-2022-37434
=====================================================================
1. Summary:
An update for rsync is now available for Red Hat Enterprise Linux 9.
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. 9) - noarch
Red Hat Enterprise Linux BaseOS (v. 9) - aarch64, ppc64le, s390x, x86_64
3. Description:
The rsync utility enables the users to copy and synchronize files locally
or across a network. Synchronization with rsync is fast because rsync only
sends the differences in files over the network instead of sending whole
files. The rsync utility is also used as a mirroring tool.
Security Fix(es):
* zlib: heap-based buffer over-read and overflow in inflate() in inflate.c
via a large gzip header extra field (CVE-2022-37434)
