May 1 2017: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- ========================================================================== Ubuntu Security Notice USN-3272-2 May 16, 2017 ghostscript regression ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - - Ubuntu 17.04 - - Ubuntu 16.10 - - Ubuntu 16.04 LTS - - Ubuntu 14.04 LTS Summary: USN-3272-1 introduced a regression in Ghostscript. Software Description: - - ghostscript: PostScript and PDF interpreter Details: USN-3272-1 fixed vulnerabilities in Ghostscript. This change introduced a regression when the DELAYBIND feature is used with the eqproc command. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that Ghostscript improperly handled parameters to the rsdparams and eqproc commands. An attacker could use these to craft a malicious document that could disable -dSAFER protections, thereby allowing the execution of arbitrary code, or cause a denial of service (application crash). (CVE-2017-8291) Kamil Frankowicz discovered a use-after-free vulnerability in the color management module of Ghostscript. An attacker could use this to cause a denial of service (application crash). (CVE-2016-10217) Kamil Frankowicz discovered a divide-by-zero error in the scan conversion code in Ghostscript. An attacker could use this to cause a denial of service (application crash). (CVE-2016-10219) Kamil Frankowicz discovered multiple NULL pointer dereference errors in Ghostscript. An attacker could use these to cause a denial of service (application crash). (CVE-2016-10220, CVE-2017-5951, CVE-2017-7207) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: ghostscript 9.19~dfsg+1-0ubuntu7.4 ghostscript-x 9.19~dfsg+1-0ubuntu7.4 libgs9 9.19~dfsg+1-0ubuntu7.4 libgs9-common 9.19~dfsg+1-0ubuntu7.4 Ubuntu 16.10: ghostscript 9.19~dfsg+1-0ubuntu6.6 ghostscript-x 9.19~dfsg+1-0ubuntu6.6 libgs9 9.19~dfsg+1-0ubuntu6.6 libgs9-common 9.19~dfsg+1-0ubuntu6.6 Ubuntu 16.04 LTS: ghostscript 9.18~dfsg~0-0ubuntu2.6 ghostscript-x 9.18~dfsg~0-0ubuntu2.6 libgs9 9.18~dfsg~0-0ubuntu2.6 libgs9-common 9.18~dfsg~0-0ubuntu2.6 Ubuntu 14.04 LTS: ghostscript 9.10~dfsg-0ubuntu10.9 ghostscript-x 9.10~dfsg-0ubuntu10.9 libgs9 9.10~dfsg-0ubuntu10.9 libgs9-common 9.10~dfsg-0ubuntu10.9 In general, a standard system update will make all the necessary changes.
