Apache NimBLE: Remote reachable assertion in ATT Read Multiple Variable Response handler

Reachable Assertion vulnerability in Apache NimBLE. A specially crafted ATT Read Multiple Variable Response (BLE_ATT_OP_READ_MULT_VAR_RSP) may trigger assert in ATT parser.

Severity is medium as this requires DUT to first send ATT Read Multiple Variable Request.

This issue affects Apache NimBLE: through 1.9.0.

Users are recommended to upgrade to version 1.10.0, which fixes the issue.
