CVE-2017-5977
The zzip_mem_entry_extra_block function in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (invalid memory read and crash) via a crafted ZIP file.
Does this matter?
Lower severity and a low EPSS score (1.73%). Track it; it rarely justifies an emergency change on its own.
