"According to the version of the gnupg2 package installed, the EulerOS
Virtualization installation on the remote host is affected by the
following vulnerability :
- mainproc.c in GnuPG before 2.2.8 mishandles the
original filename during decryption and verification
actions, which allows remote attackers to spoof the
output that GnuPG sends on file descriptor 2 to other
programs that use the '--status-fd 2' option. For
example, the OpenPGP data might represent an original
filename that contains line feed characters in
conjunction with GOODSIG or VALIDSIG status
codes.(CVE-2018-12020)
