Description OSIDB Bzimport 2025-10-23 04:01:50 UTC

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.
