Summary
cassandra-rs's non-idiomatic use of iterators leads to use after free
Details

Impact

Code that attempts to use an item (e.g., a row) returned by an iterator after the iterator has advanced to the next item will be accessing freed memory and experience undefined behaviour. Code that uses the item and then advances the iterator is unaffected. This problem has always existed.

This is a use-after-free bug, so it's rated high severity. If your code uses a pre-3.0.0 version of cassandra-rs, and uses an item returned by a cassandra-rs iterator after calling next() on that iterator, then it is vulnerable. However, such code will almost always fail immediately - so we believe it is unlikely that any code using this pattern would have reached production. For peace of mind, we recommend you upgrade anyway.

Patches

The problem has been fixed in version 3.0.0. Users should upgrade to ensure their code cannot use the problematic pattern.

Workarounds

Ensure all usage fits the expected pattern. For example, use get_first_row() rather than an iterator, or completely process an item before advancing the iterator with next().

References

None.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
