Description

lib/fsm.c in RPM 4.8.0 and earlier does not properly reset the metadata of an executable file during replacement of the file in an RPM package upgrade or deletion of the file in an RPM package removal, which might allow local users to gain privileges or bypass intended access restrictions by creating a hard link to a vulnerable file that has (1) POSIX file capabilities or (2) SELinux context information, a related issue to CVE-2010-2059.
