CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------

PACKAGE : apache
SUMMARY : Format string vulnerability with mod_ssl
DATE : 2004-08-06 12:18:00
ID : CLA-2004:857
RELEVANT
RELEASES : 8

- -------------------------------------------------------------------------

DESCRIPTION
 Ralf S. Engelschall found[1] a dangerous call[2] to ssl_log function
 in ssl_engine_log.c that could allow remote attackers to execute
 arbitrary messages via format string specifiers in certain log
 messages for HTTPS.

SOLUTION
 It is recommended that all Apache users upgrade their packages.
 
 IMPORTANT: it is necessary to manually restart the httpd server after
 upgrading the packages. In order to do this, execute the following as
 root:
 
 # service httpd stop
 
 (wait a few seconds and check with "pidof httpd" if there are any
 httpd processes running. On a busy webserver this could take a little
 longer)
 
 # service httpd start
