Fujitsu provides security patches shown in 3.
Please apply them as soon as possible.

2. Impact

1. A modified request sent by a remote attacker may consume large amounts of CPU time on the Web server and cause Denial of Service (DoS).
2. A Denial of Service (DoS) attack or arbitrary code execution on the Web server may have been caused by a malicious third party.
3. A modified request sent by a remote attacker may result in a memory leak on the Web server and cause Denial of Service (DoS).
4. A modified request sent by a remote attacker may cause Denial of Service (DoS).

4. Related information

1. CVE-2009-1891
   The mod_deflate module in Apache httpd 2.2.11 and earlier compresses large files until completion even after the associated network connection is closed, which allows remote attackers to cause a denial of service (CPU consumption).
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1891
2. CVE-2009-2412
   Multiple integer overflows in the Apache Portable Runtime (APR) library and the Apache Portable Utility library (aka APR-util) 0.9.x and 1.3.x allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger crafted calls to the (1) allocator_alloc or (2) apr_palloc function in memory/unix/apr_pools.c in APR; or crafted calls to the (3) apr_rmm_malloc, (4) apr_rmm_calloc, or (5) apr_rmm_realloc function in misc/apr_rmm.c in APR-util; leading to buffer overflows.
   NOTE: some of these details are obtained from third party information.

3. CVE-2010-1623
   Memory leak in the apr_brigade_split_line function in buckets/apr_brigade.c in the Apache Portable Runtime Utility library (aka APR-util) before 1.3.10, as used in the mod_reqtimeout module in the Apache HTTP Server and other software, allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors related to the destruction of an APR bucket.
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1623
4. CVE-2010-1452
   The (1) mod_cache and (2) mod_dav modules in the Apache HTTP Server 2.2.x before 2.2.16 allow remote attackers to cause a denial of service (process crash) via a request that lacks a path.
