RHEL 10 : gzip (RHSA-2026:61625)

medium Nessus Plugin ID 342036

Synopsis

The remote Red Hat host is missing one or more security updates for gzip.

Description

The remote Redhat Enterprise Linux 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2026:61625 advisory.

The gzip packages contain the gzip (GNU zip) data compression utility. gzip is used to compress regular files. It replaces them with files containing the .gz extension, while retaining ownership modes, access, and modification times.

Security Fix(es):

* gzip: gzip: Arbitrary file overwrite via insecure temporary file handling in gzexe utility (CVE-2026-41991)

* gzip: gzip: Information disclosure via global buffer overflow in LZH decompression (CVE-2026-41992)

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.

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

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 RHEL gzip package based on the guidance in RHSA-2026:61625.
