Description Jan Lieskovsky 2012-10-03 07:47:46 EDT
Originally, Common Vulnerabilities and Exposures assigned an identifier CVE-2011-1005 to the following vulnerability:

The safe-level feature in Ruby 1.8.6 through 1.8.6-420, 1.8.7 through 1.8.7-330, and 1.8.8dev allows context-dependent attackers to modify strings via the Exception#to_s method, as demonstrated by changing an intended pathname.

Later it was reported:
[1] http://www.openwall.com/lists/oss-security/2012/10/02/4

that the Ruby name_err_mesg_to_str() method is vulnerable to the similar flaw.

Relevant upstream patch:
