  • Ticket #354 – Description

    v2 v3  
    3434If this strange garbage was introduced when the segment was retrieved, the memory page into which the retrieval record was read should have contained all zero bits.

    36 But I believe the entire volume backup of the 1-page segment dumped its entire record onto simulated tape.  And this entire record was then reloaded.  This means the 1-page segment could have had the unexpected garbage in its on-simulated-disk record, but the garbage what shielded from view by the more restrictive bit count on the segment.

    3838At some point in its life-cycle on Multics, this 1-page segment gained what appears to be data from some other segment.  This would be a significant security violation.
