Security Fixes

CVE-2011-0188
A flaw was found in the way large amounts of memory were allocated on 64-bit systems when using the BigDecimal class. A context-dependent attacker could use this flaw to cause memory corruption, causing a Ruby application that uses the BigDecimal class to crash or, possibly, execute arbitrary code. This issue did not affect 32-bit systems.
CVE-2011-1004
A race condition flaw was found in the remove system entries method in the FileUtils module. If a local user ran a Ruby script that uses this method, a local attacker could use this flaw to delete arbitrary files and directories accessible to that user via a symbolic link attack.
CVE-2011-1005
A flaw was found in the method for translating an exception message into a string in the Exception class. A remote attacker could use this flaw to bypass safe level 4 restrictions, allowing untrusted (tainted) code to modify arbitrary, trusted (untainted) strings, which safe level 4 restrictions would otherwise prevent.
Red Hat would like to thank Drew Yao of Apple Product Security for reporting the CVE-2011-0188 issue.
All Ruby users should upgrade to these updated packages, which contain backported patches to resolve these issues.

Bug Fixes
BZ#635588
Previously, Ruby's self-test failed because of a false-positive. The erroneous result has been corrected and the test no longer fails.
BZ#635588
Ruby's self-test failed because of a bug in GNU dbm (gdbm). Until this bug is corrected, the test is omitted from Ruby's self-test to avoid this failure.
All users of Ruby are advised to upgrade to these updated packages, which correct these bugs.
