Users of Red Hat Network Satellite Server 5.0 are advised to upgrade to 5.0.2, which resolves these issues.

It is possible for clients to use any cipher suite configured by the virtual host, whether or not a certain cipher suite is selected for a specific directory. This might result in clients using a weaker encryption than originally configured.

Apache did not honour the 'SSLVerifyClient require' directive within a <Location> block if the surrounding <VirtualHost> block contained a directive 'SSLVerifyClient optional'. This allowed clients to bypass client certificate validation on servers with the above configuration.
(CAN-2005-2700)

Filip Sneppe discovered a Denial of Service vulnerability in the byte range filter handler. By requesting certain large byte ranges, a remote attacker could cause memory exhaustion in the server.
(CAN-2005-2728)

The updated libapache-mod-ssl also fixes two older Denial of Service vulnerabilities: A format string error in the ssl_log() function which could be exploited to crash the server (CAN-2004-0700), and a flaw in the SSL cipher negotiation which could be exploited to terminate a session (CAN-2004-0885). Please note that Apache 1.3 and libapache-mod-ssl are not officially supported (they are in the 'universe' component of the Ubuntu archive).

s700_800 11.04 Virtualvault 4.7 OWS (Apache 2.x) update : 

A potential security vulnerability has been identified with Apache running on HP-UX where the vulnerability could be exploited remotely to create a Denial of Service (DoS) or to bypass SSLCipherSuite restrictions.

New apache and mod_ssl packages are available for Slackware 8.1, 9.0, 9.1, 10.0, and -current to fix security issues. Apache has been upgraded to version 1.3.32 which fixes a heap-based buffer overflow in mod_proxy. mod_ssl was upgraded from version mod_ssl-2.8.19-1.3.31 to version 2.8.21-1.3.32 which corrects a flaw allowing a client to use a cipher which the server does not consider secure enough. A new PHP package (php-4.3.9) is also available for all of these platforms.

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 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 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 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. (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 allowed 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.

The remote host is missing Security Update 2004-12-02. This security update contains a number of enhancements for the following programs :

 - Apache
 - Apache2
 - AppKit
 - Cyrus IMAP
 - HIToolbox
 - Kerberos
 - Postfix
 - PSNormalizer
 - QuickTime Streaming Server
 - Safari
 - Terminal

Updated httpd packages that include fixes for two security issues, as well as other bugs, are now available.

The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server.

An issue has been discovered in the mod_ssl module when configured to use the 'SSLCipherSuite' directive in directory or location context.
If a particular location context has been configured to require a specific set of cipher suites, then a client will be able to access that location using any cipher suite allowed by the virtual host configuration. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0885 to this issue.

An issue has been discovered in the handling of white space in request header lines using MIME folding. A malicious client could send a carefully crafted request, forcing the server to consume large amounts of memory, leading to a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0942 to this issue.

Several minor bugs were also discovered, including :

  - In the mod_cgi module, problems that arise when CGI     scripts are invoked from SSI pages by mod_include using     the '#include virtual' syntax have been fixed.

  - In the mod_dav_fs module, problems with the handling of     indirect locks on the S/390x platform have been fixed.

Users of the Apache HTTP server who are affected by these issues should upgrade to these updated packages, which contain backported patches.

A vulnerability in mod_ssl was discovered by Hartmut Keil. After a renegotiation, mod_ssl would fail to ensure that the requested cipher suite is actually negotiated. The provided packages have been patched to prevent this problem.

The remote host is affected by the vulnerability described in GLSA-200410-21 (Apache 2, mod_ssl: Bypass of SSLCipherSuite directive)

    A flaw has been found in mod_ssl where the 'SSLCipherSuite' directive could     be bypassed in certain configurations if it is used in a directory or     location context to restrict the set of allowed cipher suites.
  Impact :

    A remote attacker could gain access to a location using any cipher suite     allowed by the server/virtual host configuration, disregarding the     restrictions by 'SSLCipherSuite' for that location.
  Workaround :

    There is no known workaround at this time.

The remote host is running Apple Mac OS X, but lacks Security Update 2005-009. This security update contains fixes for the following applications :
- Apache2
- Apache_mod_ssl
