 Mandriva Linux Security Advisory                         MDVSA-2011:098
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : ruby
 Date    : May 23, 2011
 Affected: Corporate 4.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities have been identified and fixed in ruby:
 
 Cross-site scripting (XSS) vulnerability in the WEBrick HTTP server
 in Ruby allows remote attackers to inject arbitrary web script or HTML
 via a crafted URI that triggers a UTF-7 error page (CVE-2010-0541).
 
 The safe-level feature in Ruby allows context-dependent attackers
 to modify strings via the Exception#to_s method, as demonstrated by
 changing an intended pathname (CVE-2011-1005).
 
 The VpMemAlloc function in bigdecimal.c in the BigDecimal class in
 Ruby does not properly allocate memory, which allows context-dependent
 attackers to execute arbitrary code or cause a denial of service
 (application crash) via vectors involving creation of a large
 BigDecimal value within a 64-bit process, related to an integer
 truncation issue. (CVE-2011-0188).
 
 The updated packages have been patched to correct this issue.
