Detail

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

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Ghostscript could be made to crash, access files, or run programs if it opened a specially crafted file.

Software Description: - ghostscript: PostScript and PDF interpreter

Details:

Tavis Ormandy discovered that Ghostscript incorrectly handled certain PostScript files. 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, execute arbitrary code, or cause a denial of service.

Update instructions:

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

Ubuntu 18.10:
ghostscript 9.26~dfsg+0-0ubuntu0.18.10.4
libgs9 9.26~dfsg+0-0ubuntu0.18.10.4

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.4
libgs9 9.26~dfsg+0-0ubuntu0.18.04.4

Ubuntu 16.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.16.04.4
libgs9 9.26~dfsg+0-0ubuntu0.16.04.4

Ubuntu 14.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.14.04.4
libgs9 9.26~dfsg+0-0ubuntu0.14.04.4

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