An off by one in the library libgs.so.8 shipped with Ghostscript in versions 8.70 and below generates an integer overflow, which in turn produces a heap corruption, resulting in a (remote) Denial of Service (crash) in several applications using this library when processing a specially crafted font. This vulnerability cannot be exploited to execute arbitrary code under GNU/Linux x86, to the best of our knowledge. Other targets, in particular Windows have not been tested and may or may not allow execution of arbitrary code.
