Red Hat alert RHSA-2004:342-01 (httpd)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated httpd packages fix security issues Advisory ID: RHSA-2004:342-01 Issue date: 2004-07-06 Updated on: 2004-07-06 Product: Red Hat Enterprise Linux Keywords: httpd mod_ssl FakeBasicAuth Cross references: Obsoletes: CVE Names: CAN-2004-0488 CAN-2004-0493 - --------------------------------------------------------------------- 1. Topic: Updated httpd packages that fix a buffer overflow in mod_ssl and a remotely triggerable memory leak are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - 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. Problem description: The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server. A stack buffer overflow was discovered in mod_ssl that could be triggered if using the FakeBasicAuth option. If mod_ssl was sent a client certificate with a subject DN field longer than 6000 characters, a stack overflow occured if FakeBasicAuth had been enabled. In order to exploit this issue the carefully crafted malicious certificate would have had to be signed by a Certificate Authority which mod_ssl is configured to trust. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0488 to this issue. A remotely triggered memory leak in the Apache HTTP Server earlier than version 2.0.50 was also discovered. This allowed a remote attacker to perform a denial of service attack against the server by forcing it to consume large amounts of memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0493 to this issue. Users of the Apache HTTP server should upgrade to these updated packages, which contain backported patches that address these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 125046 - CAN-2004-0488 mod_ssl ssl_util_uuencode_binary() stack overflow 126863 - CAN-2004-0493 folding header DoS 6.
