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.
