The update for libmodule-signature-perl issued as DSA-3261-1 introduced a regression in the handling of the --skip option of cpansign. Updated packages are now available to address this regression. For reference, the original advisory text follows. Multiple vulnerabilities were discovered in libmodule-signature-perl, a Perl module to manipulate CPAN SIGNATURE files. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-3406 John Lightsey discovered that Module::Signature could parses the unsigned portion of the SIGNATURE file as the signed portion due to incorrect handling of PGP signature boundaries. CVE-2015-3407 John Lightsey discovered that Module::Signature incorrectly handles files that are not listed in the SIGNATURE file. This includes some files in the t/ directory that would execute when tests are run. CVE-2015-3408 John Lightsey discovered that Module::Signature uses two argument open calls to read the files when generating checksums from the signed manifest. This allows to embed arbitrary shell commands into the SIGNATURE file that would execute during the signature verification process. CVE-2015-3409 John Lightsey discovered that Module::Signature incorrectly handles module loading, allowing to load modules from relative paths in @INC. A remote attacker providing a malicious module could use this issue to execute arbitrary code during signature verification.
