 Mandriva Linux Security Advisory                         MDVSA-2008:140
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : ruby
 Date    : July 9, 2008
 Affected: 2008.1
 _______________________________________________________________________
 
 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 1.9.0
 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)
 
 The updated packages have been patched to fix these issues.
