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

- Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS


Ghostscript could be made to access files if it opened a specially crafted file.

Software Description: - ghostscript: PostScript and PDF interpreter


Netanel Fisher discovered that the font handler in Ghostscript did not properly restrict privileged calls when '-dSAFER' restrictions were in effect. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could possibly use this issue to access arbitrary files.

Update instructions:

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

Ubuntu 19.04:
ghostscript 9.26~dfsg+0-0ubuntu7.2
libgs9 9.26~dfsg+0-0ubuntu7.2

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.10
libgs9 9.26~dfsg+0-0ubuntu0.18.04.10

Ubuntu 16.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.16.04.10
libgs9 9.26~dfsg+0-0ubuntu0.16.04.10

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