Ubuntu Security Notice USN-3272-2

Ubuntu Security Notice USN-3272-2
Posted May 16, 2017
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3272-2 - 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. 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. Various other issues were also addressed.

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)
