Detail

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

- Ubuntu 19.04 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

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

Software Description: - ghostscript: PostScript and PDF interpreter

Details:

Hiroki Matsukuma discovered that the PDF interpreter 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. (CVE-2019-14811, CVE-2019-14812, CVE-2019-14813, CVE-2019-14817)

Update instructions:

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

Ubuntu 19.04:
ghostscript 9.26~dfsg+0-0ubuntu7.3
libgs9 9.26~dfsg+0-0ubuntu7.3

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.11
