NeoPG

This attack on GnuPG signature verification is specific to yarn, the package manager. It can give a powerful attacker the ability to replace the Yarn installation with arbitrary code. There are additional protections in place, so if you are using Yarn, you probably do not need to worry too much about it.

This attack on GnuPG signature verification is specific to pass, the Simple Password Store. It can give the attacker access to passwords and remote code execution.

This is another attack to spoof digital signatures specific to Enigmail.

GnuPG, Enigmail, GPGTools and potentially other applications using GnuPG can be attacked with in-band signaling similar to phreaking phone lines in the 1970s (“Cap’n Crunch”). We demonstrate this by creating messages that appear to be signed by arbitrary keys.
