A directory traversal issue was found in reposync, a part of yum-utils, where reposync fails to sanitize paths in remote repository configuration files. If an attacker controls a repository, they may be able to copy files outside of the destination directory on the targeted system via path traversal. If reposync is running with heightened privileges on a targeted system, this flaw could potentially result in system compromise via the overwriting of critical system files. Version 1.1.31 and older are believed to be affected. Se ha detectado un problema de salto de directorio en reposync, de yum-utils, en el que reposync falla a la hora de sanear rutas en los archivos de configuración del repositorio remoto. • http://www.securitytracker.com/id/1041594 https://access.redhat.com/errata/RHSA-2018:2284 https://access.redhat.com/errata/RHSA-2018:2285 https://access.redhat.com/errata/RHSA-2018:2626 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10897 https://github.com/rpm-software-management/yum-utils/commit/6a8de061f8fdc885e74ebe8c94625bf53643b71c https://github.com/rpm-software-management/yum-utils/commit/7554c0133eb830a71dc01846037cc047d0acbc2c https://github.com/rpm-software-management/yum-utils/pull/43 https&# • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
