Name        : perl-Test-Signature
Product : Fedora 22
Version : 1.11
Release : 1.fc22
URL : http://search.cpan.org/dist/Test-Signature/
Summary : Automated SIGNATURE testing
Description :
Module::Signature allows you to verify that a distribution has not been
tampered with. Test::Signature lets that be tested as part of the
distribution's test suite.

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.
