Description :
This package contains a command line tool and module for checking and creating
SIGNATURE files for Perl CPAN distributions.

Update Information:

This update addresses various security issues in perl-Module-Signature as
 described below. The default behavior is also changed so as to ignore any MANIFEST.SKIP files unless a "skip" parameter is specified. An updated version of perl-Test-Signature that accounts for the changed default behaviour is included in this update.



Security issues:



 * Module::Signature before version 0.75 could be tricked into interpreting the
 unsigned portion of a SIGNATURE file as the signed portion due to faulty parsing of the PGP signature boundaries.



 * When verifying the contents of a CPAN module, Module::Signature before
 version 0.75 ignored some files in the extracted tarball that were not listed in the signature file. This included some files in the t/ directory that would execute

automatically during "make test".



 * Module::Signature before version 0.75 used two argument open() calls to read
 the files when generating checksums from the signed manifest. This allowed embedding arbitrary shell commands into the SIGNATURE file that would execute during the signature verification process.



 * Module::Signature before version 0.75 has been loading several modules at
 runtime inside the extracted module directory. Modules like Text::Diff are not guaranteed to be available on all platforms and could be added to a malicious

module so that they would load from the '.' path in @INC.
