Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : ghostscript regression (USN-3272-2)
Medium Nessus Plugin ID 100247
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-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.
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).
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).
