Ubuntu Security Notice USN-3866-1
January 23, 2019
ghostscript vulnerability
======================================================================
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

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.
