========================================================================== Ubuntu Security Notice USN-3866-2 February 21, 2019
ghostscript regression ==========================================================================
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:
USN-3866-1 introduced a regression in Ghostscript.
Software Description: - ghostscript: PostScript and PDF interpreter
Details:
USN-3866-1 fixed vulnerabilities in Ghostscript. The new Ghostscript version introduced a regression when printing certain page sizes. This update fixes the problem.
Original advisory 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+0-0ubuntu0.18.10.5 libgs9 9.26~dfsg+0-0ubuntu0.18.10.5
Ubuntu 18.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.18.04.5 libgs9 9.26~dfsg+0-0ubuntu0.18.04.5
Ubuntu 16.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.16.04.5 libgs9 9.26~dfsg+0-0ubuntu0.16.04.5
Ubuntu 14.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.14.04.5 libgs9 9.26~dfsg+0-0ubuntu0.14.04.5
In general, a standard system update will make all the necessary changes.
