Paul Szabo has reported a vulnerability in Perl "File::Path::rmtree", allowing malicious, local users to gain escalated privileges.
The vulnerability is caused due to a race condition in the way "File::Path::rmtree" changes permissions on files before deleting them. This can be exploited by creating a symbolic link to arbitrary files.
Successful exploitation may allow changing permissions or removing arbitrary files, if root uses an application using the vulnerable code to delete files.
Solution: Do not use applications, which use "File::Path::rmtree", on systems with untrusted users.
