It was discovered that RPM did not remove setuid and setgid bits set on binaries when upgrading or removing packages. A local attacker able to create hard links to binaries could use this flaw to keep those binaries on the system, at a specific version level and with the setuid or setgid bit set, even if the package providing them was upgraded or removed by a system administrator. This could have security implications if a package was upgraded or removed because of a security flaw in a setuid or setgid program. (CVE-2005-4889, CVE-2010-2059)
