Two security issues have been discovered in Ghostscript, the GPL PostScript/PDF interpreter. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-4897 It was discovered a buffer overflow that allows remote attackers to execute arbitrary code or cause a denial of service via a crafted PDF document containing a long name. CVE-2010-1628 Dan Rosenberg discovered that ghostscript incorrectly handled certain recursive Postscript files. An attacker could execute arbitrary code via a PostScript file containing unlimited recursive procedure invocations, which trigger memory corruption in the stack of the interpreter. For the stable distribution (lenny), these problems have been fixed in version 8.62.dfsg.1-3.2lenny5 For the testing distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 8.71~dfsg2-4 We recommend that you upgrade your ghostscript package.
