CVE-2018-12020

Name of the Vulnerable Software and Affected Versions GnuPG versions prior to 2.2.8

Description The issue is related to the mishandling of the original filename during decryption and verification actions in the mainproc.c component. This allows remote attackers to spoof output sent to other programs using the "--status-fd 2" option, potentially affecting the integrity of protected information. For instance, an OpenPGP data representation of an original filename with line feed characters, in conjunction with GOODSIG or VALIDSIG status codes, can be exploited.

Recommendations For versions prior to 2.2.8, update to version 2.2.8 or later to resolve the issue. As a temporary workaround, consider restricting the use of the "--status-fd 2" option until the update is applied.
