RHSA-2004-600: apache

Vulnerability Assessment Summary
Check for the version of the apache packages

Detailed Explanation for this Vulnerability Assessment

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.

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 permit a local user who is authorized to create server-side include
(SSI) files to gain the rights of a httpd child (user 'apache'). The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CVE-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 permit 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.
(CVE-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 permited by the virtual host configuration.
(CVE-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.
