CVE-2020-25467
A null pointer dereference was discovered lzo_decompress_buf in stream.c in Irzip 0.621 which allows an attacker to cause a denial of service (DOS) via a crafted compressed file.
Does this matter?
Lower severity and a low EPSS score (0.96%). Track it; it rarely justifies an emergency change on its own.
