• Ubuntu 14.04 ESM

Packages

Details

USN-3831-1 fixed vulnerabilities in Ghostscript. Ghostscript 9.26
introduced a regression when used with certain options. This update fixes
the problem.

Original advisory details:

It was discovered that Ghostscript contained multiple security issues. If a
user or automated system were tricked into processing a specially crafted
file, a remote attacker could possibly use these issues to access arbitrary
files, execute arbitrary code, or cause a denial of service.
