CVE-2021-44485

Application crash via unchecked pointer dereference

Published Apr 15, 2022 · Updated Aug 4, 2024

NULL pointer dereference in YottaDB through r1.32 and V7.0-000 allows attackers to crash the application through crafted input. The trip_gen routine in sr_port/emit_code.c dereferences a pointer without first checking whether fuzzed input left it NULL. The public record does not identify the input path or required access; successful triggering terminates the affected YottaDB process.
