Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.04 LTS - Ubuntu 17.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in GnuPG.

Software Description: - gnupg2: GNU privacy guard - a free PGP replacement - gnupg: GNU privacy guard - a free PGP replacement

Details:

Marcus Brinkmann discovered that during decryption or verification, GnuPG did not properly filter out terminal sequences when reporting the original filename. An attacker could use this to specially craft a file that would cause an application parsing GnuPG output to incorrectly interpret the status of the cryptographic operation reported by GnuPG. (CVE-2018-12020)

Lance Vick discovered that GnuPG did not enforce configurations where key certification required an offline master Certify key. An attacker with access to a signing subkey could generate certifications that appeared to be valid. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-9234)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04 LTS:
gnupg 2.2.4-1ubuntu1.1
gpg 2.2.4-1ubuntu1.1

Ubuntu 17.10:
gnupg 2.1.15-1ubuntu8.1

Ubuntu 16.04 LTS:
gnupg 1.4.20-1ubuntu3.2

Ubuntu 14.04 LTS:
gnupg 1.4.16-1ubuntu2.5

In general, a standard system update will make all the necessary changes.
