Description

This security bulletin contains information about 1 security vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4466)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Ruby 1.8.7 before patchlevel 371, 1.9.3 before patchlevel 286, and 2.0 before revision r37068 allows context-dependent attackers to bypass safe-level restrictions and modify untainted strings via the name_err_mesg_to_str API function, which marks the string as tainted, a different vulnerability than CVE-2011-1005.
