Description:
RedTeam has reported a vulnerability in Perlpodder, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to missing sanitisation of the URL received via a podcast RSS XML feed before using it as a parameter to the "system()" command. This can be exploited to inject arbitrary shell commands when the user downloads a podcast.
Successful exploitation allows execution of arbitrary commands on a perlpodder client but requires that e.g. the user is tricked into downloading a podcast based on a specially crafted RSS XML feed received from a malicious server.
The vulnerability has been reported in version 0.4. Prior versions may also be affected.
Solution:
Update to version 0.5.
