Format string vulnerability in the print_proxies function in bin/proxy.c in libproxy 0.3.1 might allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in a proxy name, as demonstrated using the http_proxy environment variable or a PAC file.

The Rocky Linux 8.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0083 advisory.

    This advisory aggregates security fixes for the libproxy SRPM in CIQ LTS 8.6. It addresses 3 CVEs:
    CVE-2012-5580, CVE-2020-26154, CVE-2012-4504.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
