CentOS Linux 7 [TuxCare] Security Update: rsync Multiple Vulnerabilities (CENTOS7:CLSA-2023:1699380056)

critical Nessus Plugin ID 352698

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2023:1699380056 advisory.

 - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. (CVE-2018-25032)

 - zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). (CVE-2022-37434)

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

Solution

Update the affected rsync package based on the guidance in TuxCare advisory CENTOS7:CLSA-2023:1699380056.
