Detail

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

- Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Evince could be made run programs as your login if it opened a specially crafted file.

Software Description: - evince: Document viewer

Details:

Felix Wilhelm discovered that Evince did not safely invoke tar when handling tar comic book (cbt) files. An attacker could use this to construct a malicious cbt comic book format file that, when opened in Evince, executes arbitrary code. Please note that this update disables support for cbt files in Evince.

Update instructions:

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

Ubuntu 17.04:
evince 3.24.0-0ubuntu1.1
evince-common 3.24.0-0ubuntu1.1

Ubuntu 16.10:
evince 3.22.0-0ubuntu1.1
evince-common 3.22.0-0ubuntu1.1

Ubuntu 16.04 LTS:
evince 3.18.2-1ubuntu4.1
evince-common 3.18.2-1ubuntu4.1

Ubuntu 14.04 LTS:
evince 3.10.3-0ubuntu10.3
evince-common 3.10.3-0ubuntu10.3

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