CVE History

CVE	Published	CVSS v3	CVSS v2
CVE-2018-16985 ↗	Sep 13, 2018Thursday, 13 September 2018, 14:29	—	5 MEDIUM
In Lizard (formerly LZ5) 2.0, use of an invalid memory address was discovered in LZ5_compress_continue in lz5_compress.c, related to LZ5_compress_fastSmall and MEM_read32. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
CVE-2018-11498 ↗	May 26, 2018Saturday, 26 May 2018, 20:29	—	6.8 MEDIUM
In Lizard v1.0 and LZ5 v2.0 (the prior release, before the product was renamed), there is an unchecked buffer size during a memcpy in the Lizard_decompress_LIZv1 function (lib/lizard_decompress_liz.h). Remote attackers can leverage this vulnerability to cause a denial of service via a crafted input file, as well as achieve remote code execution.
