Date: Wed, 09 Jul 2008 19:43:00 -0600 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2008:140 ] - Updated ruby packages fix vulnerabilities -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1891 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2662 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2663 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2664 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2725 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2726 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2376 _______________________________________________________________________ Updated Packages: Mandriva Linux 2008.1: 0e1e1ae20f5896be9834c92122ca7370 2008.1/i586/ruby-1.8.6-9p114.1mdv2008.1.i586.rpm 36d73cca1086770e7279fd1dd14e4e2f 2008.1/i586/ruby-devel-1.8.6-9p114.1mdv2008.1.i586.rpm 587b0727fe52509778bf1848e5a83de3 2008.1/i586/ruby-doc-1.8.6-9p114.1mdv2008.1.i586.rpm 04f6c795bc9b7e54f055e0da561ca045 2008.1/i586/ruby-tk-1.8.6-9p114.1mdv2008.1.i586.rpm b7598818fcbe7488f1d2e65a4881aa6a 2008.1/SRPMS/ruby-1.8.6-9p114.1mdv2008.1.src.rpm Mandriva Linux 2008.1/X86_64: 8de0e1cf1ca63db2336406dbdddf293d 2008.1/x86_64/ruby-1.8.6-9p114.1mdv2008.1.x86_64.rpm 93a8132e84bd61ef5bc79e5833075fa2 2008.1/x86_64/ruby-devel-1.8.6-9p114.1mdv2008.1.x86_64.rpm 0b6b2455e98dfbaf65cf91094fc3ca09 2008.1/x86_64/ruby-doc-1.8.6-9p114.1mdv2008.1.x86_64.rpm ca1998f680630b126d243135f765e8e2 2008.1/x86_64/ruby-tk-1.8.6-9p114.1mdv2008.1.x86_64.rpm b7598818fcbe7488f1d2e65a4881aa6a 2008.1/SRPMS/ruby-1.8.6-9p114.1mdv2008.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
