Security vulnerabilities that affected GNU Privacy Guard
SigSpoof (CVE-2018-12020) is a family of security vulnerabilities that affected the software package GNU Privacy Guard ("GnuPG") since version 0.2.2, that was released in 1998.[1] Several other software packages that make use of GnuPG were also affected, such as Pass and Enigmail.[2][1]
In un-patched versions of affected software, SigSpoof attacks allow cryptographic signatures to be convincingly spoofed, under certain circumstances.[1][3][4][2][5] This potentially enables a wide range of subsidiary attacks to succeed.[1][3][4][2][5]
