    Action Type Old Value New Value
    Changed Description LZ4 through 1.10.0 allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact when the application processes untrusted LZ4 frames. For example, LZ4F_createCDict_advanced in lib/lz4frame.c mishandles NULL checks. Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: none.
