news 28 Posted November 11, 2009 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security update Advisory ID: RHSA-2009:1579-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1579.html Issue date: 2009-11-11 CVE Names: CVE-2009-3094 CVE-2009-3095 CVE-2009-3555 ===================================================================== 1. Summary: Updated httpd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, 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 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. 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. Bugs fixed (http://bugzilla.redhat.com/): 521619 - CVE-2009-3094 httpd: NULL pointer defer in mod_proxy_ftp caused by crafted EPSV and PASV reply 522209 - CVE-2009-3095 httpd: mod_proxy_ftp FTP command injection via Authorization HTTP header 533125 - CVE-2009-3555 TLS: MITM attacks via session renegotiation 6.
