From bugzilla at redhat.com Wed Jan 6 16:29:50 2010 From: bugzilla at redhat.com (bugzilla at redhat.com) Date: Wed, 6 Jan 2010 11:29:50 -0500 Subject: [RHSA-2010:0011-01] Moderate: httpd and httpd22 security update Message-ID: <201001061629.o06GToFc032414@int-mx02.intmail.prod.int.phx2.redhat.com> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd and httpd22 security update Advisory ID: RHSA-2010:0011-01 Product: JBoss Enterprise Web Server Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0011.html Issue date: 2010-01-06 CVE Names: CVE-2009-3094 CVE-2009-3095 CVE-2009-3555 ===================================================================== 1. Summary: Updated httpd and httpd22 packages that fix multiple security issues are now available for JBoss Enterprise Web Server 1.0.0 for Red Hat Enterprise Linux 4 and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: JBoss Enterprise Web Server 1.0.0 for RHEL 4 AS - i386, x86_64 JBoss Enterprise Web Server 1.0.0 for RHEL 4 ES - i386, x86_64 JBoss Enterprise Web Server 1.0.0 for RHEL 5 Server - i386, x86_64 3. Description: The Apache HTTP Server is a popular Web server. A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handle session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update partially mitigates this flaw for SSL sessions to HTTP servers using mod_ssl by rejecting client-requested renegotiation. (CVE-2009-3555) Note: This update does not fully resolve the issue for HTTPS servers. An attack is still possible in configurations that require a server-initiated renegotiation. Refer to the following Knowledgebase article for further information: http://kbase.redhat.com/faq/docs/DOC-20491 A NULL pointer dereference flaw was found in the Apache mod_proxy_ftp module. A malicious FTP server to which requests are being proxied could use this flaw to crash an httpd child process via a malformed reply to the EPSV or PASV commands, resulting in a limited denial of service. (CVE-2009-3094) A second flaw was found in the Apache mod_proxy_ftp module. In a reverse proxy configuration, a remote attacker could use this flaw to bypass intended access restrictions by creating a carefully-crafted HTTP Authorization header, allowing the attacker to send arbitrary commands to the FTP server. (CVE-2009-3095) All users of JBoss Enterprise Web Server 1.0.0 should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, Red Hat Enterprise Linux 4 users must restart the httpd22 service, and Red Hat Enterprise Linux 5 users must restart the httpd service, for the update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5.
