RHEL 8 : rsync (RHSA-2022:7793)

critical Nessus Plugin ID 167073

Language:

Synopsis

The remote Red Hat host is missing a security update for rsync.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2022:7793 advisory.

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)

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rsync package based on the guidance in RHSA-2022:7793.
