RHSA-2003-081: zlib Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the zlib packages
Detailed Explanation for this Vulnerability Test
Updated zlib packages that fix a buffer overflow vulnerability are now
Zlib is a general-purpose, patent-free, lossless data compression
library that is used by many different programs.
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
