RHEL 8 : libproxy (RHSA-2024:6205)

critical Nessus Plugin ID 206486

Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:6205 advisory.

The libproxy packages provide a library that handles all the details of proxy configuration. The libproxy library provides a stable external API, dynamic adjustment to changing network topology, and small core footprint. It does not use external dependencies within the libproxy core, however libproxy plug-ins may have dependencies.

Security Fix(es):

* libproxy: sending more than 102400 bytes in PAC without a Content-Length present could result in buffer overflow (CVE-2020-26154)

* libproxy: uncontrolled recursion via an infinite stream response leading to stack exhaustion (CVE-2020-25219)

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 libproxy package based on the guidance in RHSA-2024:6205.
