Summary
Red Hat Security Advisory: : Updated zlib packages fix gzprintf buffer overflow vulnerability

Notes

Topic
Updated zlib packages are now available which fix a buffer overflow vulnerability.
Details
Zlib is a general-purpose, patent-free, lossless data compression library 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.

Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
