A security oversight has been discovered in LedgerSMB 1.3 which could
allow a malicious user to cause a denial of service against LedgerSMB
or otherwise affect the way in which certain forms of data would get
entered. In most cases we do not believe this to be particularly
severe in the absence of poor internal process controls. Users in
some jurisdictions however may need to take this more seriously (see
full details below).
