Gentoo Linux Security Advisory 201708-6 - Multiple vulnerabilities have been found in GPL Ghostscript, the worst of which can resulting in the execution of arbitrary code. Versions less than 9.21 are affected.
0b3ca6002a226ed12c3311cfe48ae342dfc6ea37d1c8bdf16eaa87d29c01d47eUbuntu 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.

Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed. Security Fix: It was found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection.

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. 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. Various other issues were also addressed.
