Debian: New ghostscript packages fix several vulnerabilities

Two security issues have been discovered in Ghostscript, the GPL PostScript/PDF interpreter. 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. 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. Updated packages are available from security.debian.org.

Debian Bug     : 584516

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.
