(CVE-2009-0196)

USN-743-1 provided updated ghostscript and gs-gpl packages to fix two
security vulnerabilities. This update corrects the same vulnerabilities in
the gs-esp package.

Original advisory details:
 It was discovered that Ghostscript contained multiple integer overflows in
 its ICC color management library. If a user or automated system were
 tricked into opening a crafted Postscript file, an attacker could cause a
 denial of service or execute arbitrary code with privileges of the user
 invoking the program. (CVE-2009-0583)

 It was discovered that Ghostscript did not properly perform bounds
 checking in its ICC color management library. If a user or automated
 system were tricked into opening a crafted Postscript file, an attacker
 could cause a denial of service or execute arbitrary code with privileges
 of the user invoking the program. (CVE-2009-0584)");
