Description Quality Assurance univentionstaff 2018-08-09 10:20:06 CEST
New Debian gnupg2 2.0.26-6+deb8u2 fixes:
This update addresses the following issue(s):
* 
CVE_2018-9234 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)

2.0.26-6+deb8u2 (Fri, 08 Jun 2018 20:58:33 +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)
