GnuPG could be made to incorrectly interpret the status of the cryptographic operation if it received specially crafted file.

Summary

GnuPG could be made to incorrectly interpret the status of the

cryptographic operation if it received specially crafted file.

Software Description:

- gnupg: GNU privacy guard - a free PGP replacement

Details:

USN-3675-1 fixed a vulnerability in GnuPG. This update provides

the corresponding update for Ubuntu 12.04 ESM.

Original advisory 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)
