CVE-2018-12020

Upstream information

CVE-2018-12020 at MITRE

Description

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.

Note from the SUSE Security Team

This issue affects the GnuPG CLI in non-default configurations. While zypper/libzypp use GnuPG for repository signature verification, they are not affected: In SLE 12 and earlier, verbose output is not configured or requested via the command line. In SLE 15, libzypp uses gpgme as an interface to GnuPG.
