Description Vasyl Kaigorodov 2015-04-08 12:51:02 UTC

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.
