CVE-2017-2623 – rpm-ostree-client: fails to check gpg package signatures when layering

https://notcve.org/view.php?id=CVE-2017-2623

It was discovered that rpm-ostree and rpm-ostree-client before 2017.3 fail to properly check GPG signatures on packages when doing layering. Packages with unsigned or badly signed content could fail to be rejected as expected. This issue is partially mitigated on RHEL Atomic Host, where certificate pinning is used by default. Se ha descubierto que rpm-ostree y rpm-ostree-client en versiones anteriores a la 2017.3 no comprueban correctamente las firmas GPG en los paquetes al crear las capas. Los paquetes con contenido sin firmar o mal firmado podrían no ser rechazados tal y como se esperaría. • http://www.securityfocus.com/bid/96558 https://access.redhat.com/errata/RHSA-2017:0444 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2623 https://access.redhat.com/security/cve/CVE-2017-2623 https://bugzilla.redhat.com/show_bug.cgi?id=1422157 • CWE-295: Improper Certificate Validation •
