========================================================================== 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:
