========================================================================== Ubuntu Security Notice USN-3866-3 February 26, 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-3866-2 introduced a regression in Ghostscript. Software Description: - ghostscript: PostScript and PDF interpreter Details: USN-3866-2 fixed a regression in Ghostscript. The Ghostscript update introduced a new regression that resulted in certain pages being printed with a blue background. 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+0-0ubuntu0.18.10.7 libgs9 9.26~dfsg+0-0ubuntu0.18.10.7 Ubuntu 18.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.18.04.7 libgs9 9.26~dfsg+0-0ubuntu0.18.04.7 Ubuntu 16.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.16.04.7 libgs9 9.26~dfsg+0-0ubuntu0.16.04.7 Ubuntu 14.04 LTS: ghostscript 9.26~dfsg+0-0ubuntu0.14.04.7 libgs9 9.26~dfsg+0-0ubuntu0.14.04.7 In general, a standard system update will make all the necessary changes.
