Fedora 10: FEDORA-2009-12604 critical: httpd session flaws mitigated

This update contains the latest stable release of Apache httpd. Three security fixes are included, along with several minor bug fixes. 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. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2009-12604 2009-12-04 22:40:20 -------------------------------------------------------------------------------- Name : httpd Product : Fedora 10 Version : 2.2.14 Release : 1.fc10 URL : https://httpd.apache.org/ Summary : Apache HTTP Server Description : The Apache HTTP Server is a powerful, efficient, and extensible web server. -------------------------------------------------------------------------------- Update Information: This update contains the latest stable release of Apache httpd. Three security fixes are included, along with several minor bug fixes. 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 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 orPASV 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) See the upstream changes file for further information: -------------------------------------------------------------------------------- ChangeLog: * Thu Dec 3 2009 Joe Orton - 2.2.14-1 - update to 2.2.14 - Requires(pre): httpd in mod_ssl subpackage (#543275) - add partial security fix for CVE-2009-3555 (#533125) - add condrestart in posttrans (#491567) * Sun Aug 23 2009 Joe Orton 2.2.13-1 - update to 2.2.13 - add delaycompress to logrotate config * Mon Feb 9 2009 Joe Orton 2.2.11-2 - update to 2.2.11 (#482960) - Require apr-util-ldap (#471898) -------------------------------------------------------------------------------- References: [ 1 ] Bug #521619 - CVE-2009-3094 httpd: NULL pointer defer in mod_proxy_ftp caused by crafted EPSV and PASV reply https://bugzilla.redhat.com/show_bug.cgi?id=521619 [ 2 ] Bug #522209 - CVE-2009-3095 httpd: mod_proxy_ftp FTP command injection via Authorization HTTP header https://bugzilla.redhat.com/show_bug.cgi?id=522209 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
