This update of ruby fixes :

  - a possible information leakage. (CVE-2008-1145) 

  - a directory traversal bug in WEBrick. (CVE-2008-1891) 

  - various memory corruptions and integer overflows in     array and string handling. (CVE-2008-2662,     CVE-2008-2663, CVE-2008-2664, CVE-2008-2725,     CVE-2008-2726, CVE-2008-2727, CVE-2008-2728)

The remote instance of WEBrick, a standard library of Ruby to implement HTTP servers, allows an attacker to view the source of CGI scripts hosted by the affected application by appending to the URL certain characters, such as '+', '%2b', '.', '%2e', or '%20'. 

Note that successful exploitation may be dependent on the underlying remote filesystem, for example FAT32 and NTFS.

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)

Directory traversal vulnerability in WEBrick in Ruby 1.9.0 and earlier, when using NTFS or FAT filesystems, allows remote attackers to read arbitrary CGI files via a trailing (1) + (plus), (2) %2b (encoded plus), (3) . (dot), (4) %2e (encoded dot), or (5) %20 (encoded space) character in the URI, possibly related to the WEBrick::HTTPServlet::FileHandler and WEBrick::HTTPServer.new functionality and the :DocumentRoot option. (CVE-2008-1891)

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.
(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.
(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. (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.
(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)
