Descriptions

A UNIX Symbolic Link (Symlink) Following vulnerability in chkstat of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15, SUSE Linux Enterprise Server 11 set permissions intended for specific binaries on other binaries because it erroneously followed symlinks. The symlinks can't be controlled by attackers on default systems, so exploitation is difficult. This issue affects: SUSE Linux Enterprise Server 12 permissions versions prior to 2015.09.28.1626-17.27.1. SUSE Linux Enterprise Server 15 permissions versions prior to 20181116-9.23.1. SUSE Linux Enterprise Server 11 permissions versions prior to 2013.1.7-0.6.12.1.

Una vulnerabilidad de tipo UNIX Symbolic Link (Symlink) Following en chkstat de SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15, SUSE Linux Enterprise Server 11 establece permisos previstos para binarios específicos en otros binarios porque seguía erróneamente enlaces simbólicos. Los atacantes no pueden controlar los enlaces simbólicos en los sistemas predeterminados, por lo que la explotación es difícil. Este problema afecta: Los permisos de SUSE Linux Enterprise Server 12 versiones anteriores a 2015.09.28.1626-17.27.1. Los permisos de SUSE Linux Enterprise Server 15 versiones anteriores a 20181116-9.23.1. Los permisos de SUSE Linux Enterprise Server 11 versiones anteriores a 2013.1.7-0.6.12.1.
