The _xrealloc function in xlsp_xmalloc.c in OpenSLP 2.0.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a large number of crafted packets, which triggers a memory allocation failure.
The product dereferences a pointer that it expects to be valid but is NULL.
