The remote SuSE 11 host is missing one or more security updates.
The ruby interpreter received a fix for a security issue :
- Ruby's $SAFE mechanism enables untrusted user codes to
run in $SAFE >= 4 mode. This is a kind of sandboxing so
some operations are restricted in that mode to protect
other data outside the sandbox. (CVE-2012-4466)
The problem found was around this mechanism.
Exception#to_s, NameError#to_s, and name_err_mesg_to_s()
interpreter-internal API was not correctly handling the
$SAFE bits so a String object which is not tainted can
destructively be marked as tainted using them. By using
this an untrusted code in a sandbox can modify a
formerly-untainted string destructively.
