Redhat : Updated httpd packages fix mod_ssl security flaw



Security Advisory - RHSA-2004:349-10
------------------------------------------------------------------------------
Summary:
Updated httpd packages fix mod_ssl security flaw

Updated httpd packages that include a security fix for mod_ssl and various
enhancements are now available.

Description:
The Apache HTTP server is a powerful, full-featured, efficient, and
freely-available Web server.

An input filter bug in mod_ssl was discovered in Apache httpd version
2.0.50 and earlier.  A remote attacker could force an SSL connection to be
aborted in a particular state and cause an Apache child process to enter an
infinite loop, consuming CPU resources.  The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0748 to
this issue.

Additionally, this update includes the following enhancements and bug fixes:

- included an improved version of the mod_cgi module that correctly handles    
  concurrent output on stderr and stdout

- included support for direct lookup of SSL variables using %{SSL:...}
  from mod_rewrite, or using %{...}s from mod_headers

- restored support for use of SHA1-encoded passwords

- added the mod_ext_filter module

Users of the Apache HTTP server should upgrade to these updated packages,
which contain backported patches that address these issues.
