http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a denial of service (crash due to a NULL pointer dereference) by returning a crafted response that lacks a space character.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
