Details

Matthew Palmer discovered an underflow flaw in apr-util as included in
Apache. An attacker could cause a denial of service via application crash
in Apache using a crafted SVNMasterURI directive, .htaccess file, or when
using mod_apreq2. This issue only affected Ubuntu 6.06 LTS. (CVE-2009-0023)

Sander de Boer discovered that mod_proxy_ajp would reuse connections when
a client closed a connection without sending a request body. A remote
attacker could exploit this to obtain sensitive response data. This issue
only affected Ubuntu 9.04. (CVE-2009-1191)

Jonathan Peatfield discovered that Apache did not process Includes options
correctly. With certain configurations of Options and AllowOverride, a
local attacker could use an .htaccess file to override intended
restrictions and execute arbitrary code via a Server-Side-Include file.
This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04. (CVE-2009-1195)

It was discovered that the XML parser did not properly handle entity
expansion. A remote attacker could cause a denial of service via memory
resource consumption by sending a crafted request to an Apache server
configured to use mod_dav or mod_dav_svn. This issue only affected Ubuntu
6.06 LTS. (CVE-2009-1955)

C. Michael Pilato discovered an off-by-one buffer overflow in apr-util when
formatting certain strings. For big-endian machines (powerpc, hppa and
sparc in Ubuntu), a remote attacker could cause a denial of service or
information disclosure leak. All other architectures for Ubuntu are not
considered to be at risk. This issue only affected Ubuntu 6.06 LTS.
(CVE-2009-1956)
