"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2026:63386 advisory.

    Red Hat Satellite is a system management solution that allows organizations
    to configure and maintain their systems without the necessity to provide
    public Internet access to their servers or other client systems. It
    performs provisioning and configuration management of predefined standard
    operating environments.

    * python3.12-aiohttp: AIOHTTP: HTTP Request Smuggling via WebSocket Upgrade (CVE-2026-69243)

    * python3.12-aiohttp: AIOHTTP: Denial of Service via malformed HTTP responses (CVE-2026-69244)

    * openvox-server: Eclipse Jetty: Information disclosure due to retained HTTP/1.1 trailers across
    connections (CVE-2026-10051)

    * openvox-server: jackson-core: Denial of Service via incomplete fix in async JSON parser (CVE-2026-68494)

    * python3.12-aiohttp: AIOHTTP: Arbitrary code execution via untrusted input to CookieJar.load()
    (CVE-2026-34993)

    * ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution

    * puppetserver: jackson-databind: Arbitrary code execution via PolymorphicTypeValidator bypass
    (CVE-2026-54512)

    * ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for
    CVE-2026-11332) (CVE-2026-16493)

    * rubygem-jwt: ruby-jwt: Authentication bypass due to empty key in HMAC verification (CVE-2026-45363)

    Bug Fix(es):

    * Satellite 6.17 upgrade, foreman-installer reports errors in /var/log/dnf.rpm.log Selected scenario is
    DISABLED, can not continue (SAT-48693)

    * Non-default umask breaks IoP assets directory permissions (SAT-48690)

    * Unable to upgrade to Red Hat Satellite 6.17 as rubygem-foreman_maintain is not getting updated after
    running satellite-maintain self-upgrade (SAT-48692)

    * Remove Orphan fails with package_signing_fingerprint cannot be nil error after upgrade to Red Hat
    satellite 6.18.2 (SAT-48691)

    * Issue when creating filter in content view using openssl package (SAT-48697)

    * Unable to save bookmark report under Hosts  All Hosts  Compliance  Reports (SAT-49372)
