Detail

Problem Description:

Updated apache and mod_ssl packages that fix various minor security issues and bugs in the Apache Web server are now available for Red Hat Enterprise Linux 2.1.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

The Apache HTTP Server is a powerful, full-featured, efficient, and freely-available Web server. The mod_ssl module provides strong cryptography for the Apache Web server via the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.

A buffer overflow was discovered in the mod_include module. This flaw could allow a local user who is authorized to create server-side include (SSI) files to gain the privileges of a httpd child (user 'apache'). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0940 to this issue.

The mod_digest module does not properly verify the nonce of a client response by using a AuthNonce secret. This could allow a malicious user who is able to sniff network traffic to conduct a replay attack against a website using Digest protection. Note that mod_digest implements an older version of the MD5 Digest Authentication specification, which is known not to work with modern browsers. This issue does not affect mod_auth_digest. (CAN-2003-0987).

An issue has been discovered in the mod_ssl module when configured to use the "SSLCipherSuite" directive in a directory or location context. If a particular location context has been configured to require a specific set of cipher suites, then a client is able to access that location using any cipher suite allowed by the virtual host configuration. (CAN-2004-0885).

Several bugs in mod_ssl were also discovered, including:

- - memory leaks in SSL variable handling

- - possible crashes in the dbm and shmht session caches

Red Hat Enterprise Linux 2.1 users of the Apache HTTP Server should upgrade to these erratum packages, which contains Apache version 1.3.27 with backported patches correcting these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date

For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system:

http://www.redhat.com/docs/manuals/enterprise/

5. Bug IDs fixed (http://bugzilla.redhat.com/ for more info):

131360 - RHEL 2.1 mod_ssl missing shmht fixes 134826 - CAN-2004-0885 SSLCipherSuite bypass 137417 - CAN-2004-0940 mod_include local escalation 137419 - CAN-2003-0987 mod_digest nonce checking flaw

Open Source Vulnerability Database (OSVDB)

Id Description
12881 OpenBSD httpd mod_include Local Overflow

A local overflow exists in OpenBSD. The mod_include module for httpd fails to properly validate the length of user supplied tag strings prior to copying them to a local buffer resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of integrity.
11003 Apache HTTP Server mod_include get_tag() Function Local Overflow

A local overflow exists in the Apache HTTP server mod_include module (compiled in by default). The get_tag() function in mod_include.c contains a logic flaw resulting in a buffer overflow. A local attacker who is authorized to create server side include (SSI) files, can create a specially crafted HTML file and cause arbitrary code execution with the privileges of the httpd child process, resulting in a loss of integrity.
10637 Apache HTTP Server mod_ssl SSLCipherSuite Access Restriction Bypass

Apache mod_ssl SSL CipherSuite contains a flaw that may allow a malicious user to bypass SSL CipherSuite access restrictions. The issue is triggered when the SSL CipherSuite directive is used with a directory context to require a restricted set of cipher suites. An attacker can use an alternate ciphersuite possibly allowing them to bypass access restrictions resulting in a loss of confidentiality and/or integrity.
3819 Apache HTTP Server mod_digest Cross Realm Credential Replay

Apache mod_digest contains a flaw that may allow a malicious user to conduct replay attack against a website using htdigest protection. The issue is triggered when sending the digest authentication credentials again to a different website. It is possible that the flaw may allow gain unauthorised access to other websites. resulting in a loss of confidentiality, integrity, and/or availability.
