RedHat: RHSA-2010-0659:01 Moderate: httpd security and bug fix update
Summary
The Apache HTTP Server is a popular web server.
A flaw was discovered in the way the mod_proxy module of the Apache HTTP
Server handled the timeouts of requests forwarded by a reverse proxy to the
back-end server. If the proxy was configured to reuse existing back-end
connections, it could return a response intended for another user under
certain timeout conditions, possibly leading to information disclosure.
(CVE-2010-2791)
A flaw was found in the way the mod_dav module of the Apache HTTP Server
handled certain requests. If a remote attacker were to send a carefully
crafted request to the server, it could cause the httpd child process to
crash. (CVE-2010-1452)
This update also fixes the following bugs:
* numerous issues in the INFLATE filter provided by mod_deflate. "Inflate
error -5 on flush" errors may have been logged. This update upgrades
mod_deflate to the newer upstream version from Apache HTTP Server 2.2.15.
(BZ#625435)
* the response would be corrupted if mod_filter applied the DEFLATE filter
to a resource requiring a subrequest with an internal redirect. (BZ#625451)
* the OID() function used in the mod_ssl "SSLRequire" directive did not
correctly evaluate extensions of an unknown type. (BZ#625452)
All httpd users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the httpd daemon must be restarted for the update to take effect.
Summary
