CVE-2017-14034Date: (C)2017-11-22   (M)2023-12-22


The restore_tqb_pixels function in hevc_filter.c in libavcodec, as used in libbpg 0.9.7 and other products, miscalculates a memcpy destination address, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact.
