<title>Perl Module-Signature module: Arbitrary code execution</title>

<synopsis>The Module-Signature module for Perl has insufficient path checks,

allowing a remote attacker to execute arbitrary Perl code.

<p>The Perl Module::Signature module adds signing capabilities to CPAN

modules.

|

|
|
<p>The ‘cpansign verify’ command will automatically download keys and
|
|||
|
|
use them to check the signature of CPAN packages via the SIGNATURE file.
|
|||
|
|
If an attacker were to replace this (SHA1) with a special unknown cipher
|
|||
|
|
(e.g. ‘Special’) and were to include in the distribution a
|
|||
|
|
‘Digest/Special.pm’, the code in this Perl module would be executed
|
|||
|
|
when ‘cpansign -verify’ is run.

privileges of the process.
