Fedora 21: FEDORA-2015-5833 Moderate: perl-Test-Signature Security Risks

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 behavior is included in this update. Security issues: * Module::Signature before version 0.75 could be tricked [More...]. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2015-5833 2015-04-09 04:58:00 -------------------------------------------------------------------------------- Name : perl-Test-Signature Product : Fedora 21 Version : 1.11 Release : 1.fc21 URL : https://metacpan.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 behavior 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 generatingchecksums 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. -------------------------------------------------------------------------------- ChangeLog: * Wed Apr 8 2015 Paul Howarth - 1.11-1 - Update to 1.11 - Compatibility with Module::Signature 0.75+ - Classify buildreqs by usage - Don't use macros for commands - Avoid clobbering ~/.gnupg for local builds - Make %files list more explicit - Drop %defattr, redundant since rpm 4.4 - Import upstream's GPG key in %prep so we don't need to fetch it from a keyserver when running the signature test * Tue Aug 26 2014 Jitka Plesnikova - 1.10-18 - Perl 5.20 rebuild -------------------------------------------------------------------------------- References: [ 1 ] Bug #1209911 - perl-Module-Signature: unsigned files interpreted as signed in some circumstances https://bugzilla.redhat.com/show_bug.cgi?id=1209911 [ 2 ] Bug #1209915 - perl-Module-Signature: arbitrary code execution during test phase https://bugzilla.redhat.com/show_bug.cgi?id=1209915 [ 3 ] Bug #1209917 - perl-Module-Signature: arbitrary code execution when verifying module signatures https://bugzilla.redhat.com/show_bug.cgi?id=1209917 [ 4 ] Bug #1209918 - perl-Module-Signature: arbitrary modules loading in some circumstances https://bugzilla.redhat.com/show_bug.cgi?id=1209918 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
