Description Quality Assurance univentionstaff 2018-08-09 12:26:59 CEST 
New Debian gnupg 1.4.18-7+deb8u5 fixes:
This update addresses the following issue(s):
* 
CVE_2018-6829 is open
* 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)

1.4.18-7+deb8u5 (Fri, 08 Jun 2018 21:55:06 +0200) * Non-maintainer upload by the Security Team. * gpg: Sanitize diagnostic with the original file name (CVE-2018-12020)
* CVE-2018-12020 gnupg2: Improper sanitization of filenames allows for the display of fake status messages and the bypass of signature verification (CVE-2018-12020)
