New apache and mod_ssl packages are available for Slackware 8.1, 9.0, 9.1, 10.0, and -current to fix security issues. Apache has been upgraded to version 1.3.32 which fixes a heap-based buffer overflow in mod_proxy. mod_ssl was upgraded from version mod_ssl-2.8.19-1.3.31 to version 2.8.21-1.3.32 which corrects a flaw allowing a client to use a cipher which the server does not consider secure enough. A new PHP package (php-4.3.9) is also available for all of these platforms.
