Details

Netanel Fisher discovered that the font handler in Ghostscript did not
properly restrict privileged calls when ‘-dSAFER’ restrictions were in
effect. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could possibly use this issue to
access arbitrary files.
