Perlpodder Shell Command Injection Vulnerability

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/20238/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Perlpodder 0.x
http://secunia.com/product/10110/

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.
