FreeBSD : perl -- Directory Permissions Race Condition (4a99d61c-f23a-11dd-9f55-0030843d3802)

low Nessus Plugin ID 35582

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

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.

Solution

Update the affected package.
