30 May 2019

evolution-data-server vulnerability

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

  • Ubuntu 18.04 LTS
  • Ubuntu 16.04 LTS


Evolution Data Server would sometimes display email content as encrypted when it was not.

Software Description

  • evolution-data-server - Evolution suite data server


Marcus Brinkmann discovered that Evolution Data Server did not correctly interpret the output from GPG when decrypting encrypted messages. Under certain circumstances, this could result in displaying clear-text portions of encrypted messages as though they were encrypted.
