Secunia reports:
Paul Szabo has reported a vulnerability in Perl File::Path::rmtree, which potentially can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a race condition in the way File::Path::rmtree handles directory permissions when cleaning up directories. This can be exploited by replacing an existing sub directory in the directory tree with a symbolic link to an arbitrary file.
Successful exploitation may allow changing permissions of arbitrary files, if root uses an application using the vulnerable code to delete files in a directory having a world-writable sub directory.
