paul Posted July 22, 2010 Report Share Posted July 22, 2010 Multiple vulnerabilities has been found and corrected in ghostscript: Stack-based buffer overflow in the errprintf function in base/gsmisc.c in ghostscript 8.64 through 8.70 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PDF file, as originally reported for debug logging code in gdevcups.c in the CUPS output driver (CVE-2009-4270). Buffer overflow in gs/psi/iscan.c in Ghostscript 8.64 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDF document containing a long name (CVE-2009-4897). Ghostscript 8.64, 8.70, and possibly other versions allows context-dependent attackers to execute arbitrary code via a PostScript file containing unlimited recursive procedure invocations, which trigger memory corruption in the stack of the interpreter (CVE-2010-1628). As a precaution ghostscript has been rebuilt to link against the system libpng library which was fixed with MDVSA-2010:133 Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program.
