CVE-2011-4315
Heap-based buffer overflow in compression-pointer processing in core/ngx_resolver.c in nginx before 1.0.10 allows remote resolvers to cause a denial of service (daemon crash) or possibly have unspecified other impact via a long response.
Does this matter?
Lower severity and a low EPSS score (5.96%). Track it; it rarely justifies an emergency change on its own.
