CVE-2018-18384
Info-ZIP UnZip 6.0 has a buffer overflow in list.c, when a ZIP archive has a crafted relationship between the compressed-size value and the uncompressed-size value, because a buffer size is 10 and is supposed to be 12.
Does this matter?
Lower severity and a low EPSS score (2.59%). Track it; it rarely justifies an emergency change on its own.
