-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:207 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : perl-Module-Signature Date : April 27, 2015 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Updated perl-Module-Signature package fixes the following security vulnerabilities reported by John Lightsey: Module::Signature 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 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 When generating checksums from the signed manifest, Module::Signature used two argument open() calls to read the files. This allowed embedding arbitrary shell commands into the SIGNATURE file that would execute during the signature verification process. Several modules were loaded 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. _______________________________________________________________________ References: http://advisories.mageia.org/MGASA-2015-0160.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 47149b012bb749c0bad31476a85d7d37 mbs1/x86_64/perl-Module-Signature-0.730.0-1.1.mbs1.noarch.rpm e10863123658798234fc8304bda196b5 mbs1/SRPMS/perl-Module-Signature-0.730.0-1.1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
