Title: Ghostscript vulnerabilities
Summary: Several security issues were fixed in Ghostscript.
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.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
