 Problem Description:
 
 Multiple vulnerabilities have been found in the Ruby interpreter and
 in Webrick, the webserver bundled with Ruby.
 
 Directory traversal vulnerability in WEBrick in Ruby 1.8 before
 1.8.5-p115 and 1.8.6-p114, and 1.9 through 1.9.0-1, when running on
 systems that support backslash (\) path separators or case-insensitive
 file names, allows remote attackers to access arbitrary files via
 (1) ..%5c (encoded backslash) sequences or (2) filenames that match
 patterns in the :NondisclosureName option. (CVE-2008-1145)
 
 Multiple integer overflows in the rb_str_buf_append function in
 Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before
 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2
 allow context-dependent attackers to execute arbitrary code or
 cause a denial of service via unknown vectors that trigger memory
 corruption, a different issue than CVE-2008-2663, CVE-2008-2664,
 and CVE-2008-2725. (CVE-2008-2662)
 
 Multiple integer overflows in the rb_ary_store function in Ruby
 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230,
 and 1.8.7 before 1.8.7-p22 allow context-dependent attackers to
 execute arbitrary code or cause a denial of service via unknown
 vectors, a different issue than CVE-2008-2662, CVE-2008-2664, and
 CVE-2008-2725. (CVE-2008-2663)
 
 The rb_str_format function in Ruby 1.8.4 and earlier, 1.8.5 before
 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0
 before 1.9.0-2 allows context-dependent attackers to trigger memory
 corruption via unspecified vectors related to alloca, a different issue
 than CVE-2008-2662, CVE-2008-2663, and CVE-2008-2725. (CVE-2008-2664)
 
 Integer overflow in the rb_ary_splice function in Ruby 1.8.4
 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230,
 and 1.8.7 before 1.8.7-p22 allows context-dependent attackers to
 trigger memory corruption via unspecified vectors, aka the REALLOC_N
 variant, a different issue than CVE-2008-2662, CVE-2008-2663, and
 CVE-2008-2664. (CVE-2008-2725)
 
 Integer overflow in the rb_ary_splice function in Ruby 1.8.4 and
 earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before
 1.8.7-p22, and 1.9.0 before 1.9.0-2 allows context-dependent attackers
 to trigger memory corruption, aka the beg + rlen issue. (CVE-2008-2726)
 
 Integer overflow in the rb_ary_fill function in array.c in Ruby before
 revision 17756 allows context-dependent attackers to cause a denial
 of service (crash) or possibly have unspecified other impact via a
 call to the Array#fill method with a start (aka beg) argument greater
 than ARY_MAX_SIZE. (CVE-2008-2376)
 
 The updated packages have been patched to fix these issues.
