Description of problem:

The Diatheke CGI allows arbitrary command execution in the context of the webserver, e.g. www-data by simply abusing the range parameter.

For example, &range=yes will consume tons of resources on the affected webserver. Escalation of privleges and command shells are left as an exercise to the reader.

From Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466449

Stack-based buffer overflow in the zseticcspace function in zicc.c in Ghostscript 8.61 and earlier allows remote attackers to execute arbitrary code via a postscript (.ps) file containing a long Range array in a .seticcspace operator.

The Kerberos 4 support in KDC in MIT Kerberos 5 (krb5kdc) does not properly clear the unused portion of a buffer when generating an error message, which might allow remote attackers to obtain sensitive information, aka "Uninitialized stack values."

KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.
