Detail

Problem Description:

Updated httpd packages that fix two security issues are now available for
Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

The Apache HTTP Server is a popular and freely-available Web server.

A flaw was found in the handling of compression structures between mod_ssl
and OpenSSL. If too many connections were opened in a short period of time,
all system memory and swap space would be consumed by httpd, negatively
impacting other processes, or causing a system crash. (CVE-2008-1678)

Note: The CVE-2008-1678 issue did not affect Red Hat Enterprise Linux 5
prior to 5.3. The problem was introduced via the RHBA-2009:0181 errata in
Red Hat Enterprise Linux 5.3, which upgraded OpenSSL to the newer 0.9.8e
version.

A flaw was found in the handling of the "Options" and "AllowOverride"
directives. In configurations using the "AllowOverride" directive with
certain "Options=" arguments, local users were not restricted from
executing commands from a Server-Side-Include script as intended.
(CVE-2009-1195)

All httpd users should upgrade to these updated packages, which contain
backported patches to resolve these issues. Users must restart httpd for
this update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

447268 - CVE-2008-1678 httpd: mod_ssl per-connection memory leak for connections with zlib compression
489436 - CVE-2009-1195 AllowOverride Options=IncludesNoExec allows Options Includes
497077 - memory leak in httpd

Title:	Memory leak in the zlib_stateful_init function in crypto/comp/c_zlib.c in libssl in OpenSSL 0.9.8f through 0.9.8h allows remote attackers to cause a denial of service (memory consumption) via multiple calls, as demonstrated by initial SSL client handshakes to the Apache HTTP Server mod_ssl that specify a compression algorithm.
