Description
Some weaknesses have been reported in RPM Package Manager, which can be exploited by malicious, local users to gain escalated privileges.
1) The application does not properly remove e.g. the setuid and setgid bits from binaries when upgrading or removing a package, which can be exploited to gain escalated privileges by creating hardlinks to the old binary.
2) The application does not properly update the POSIX file capabilities when e.g. erasing or renaming a binary, which can be exploited to keep the previous capabilities by creating hardlinks to the old binary.
