Description Mark J. Cox (Product Security) 2003-03-26 04:24:11 EST
The function gzprintf within zlib, when called with a string longer than
Z_PRINTF_BUFZISE (= 4096 bytes), can overflow without giving a warning.

zlib-1.1.4 and earlier exhibit this behavior. There are no known exploits
of the gzprintf overrun, and only a few programs, including rpm2html
and gimp-print, are known to use the gzprintf function.

The problem has been fixed by checking the length of the output string
within gzprintf. 

This is CAN-2003-0107 and will be RHSA-2003:081
