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.
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.
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. (CVE-2011-1005)
All Ruby users should upgrade to these updated packages, which contain
