Vulnerability Assessment Details

RHSA-2003-081: zlib

Vulnerability Assessment Summary
Check for the version of the zlib packages

Detailed Explanation for this Vulnerability Assessment

Updated zlib packages that fix a buffer overflow vulnerability are now
available.

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
within gzprintf.
