+nscd: Stack-based buffer overflow in netgroup cache
+
+If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted
+by client requests then a subsequent client request for netgroup data
+may result in a stack-based buffer overflow.  This flaw was introduced
+in glibc 2.15 when the cache was added to nscd.
+
+This vulnerability is only present in the nscd binary.

+nscd: Null pointer crash after notfound response
+
+If the Name Service Cache Daemon's (nscd) cache fails to add a not-found

+pointer dereference.  This flaw was introduced in glibc 2.15 when the
+cache was added to nscd.

+nscd: netgroup cache may terminate daemon on memory allocation failure
+
+The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or
+xrealloc and these functions may terminate the process due to a memory
+allocation failure resulting in a denial of service to the clients.  The
+flaw was introduced in glibc 2.15 when the cache was added to nscd.
+
+This vulnerability is only present in the nscd binary.
+
+Subsequent refactoring of the netgroup cache only added more uses of
+xmalloc and xrealloc. Uses of xmalloc and xrealloc in other parts of
+nscd only occur during startup of the daemon and so are not affected by
+client requests that could trigger an out of memory followed by
+termination.

+nscd: netgroup cache assumes NSS callback uses in-buffer strings
+
+The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory
+when the NSS callback does not store all strings in the provided buffer.
+The flaw was introduced in glibc 2.15 when the cache was added to nscd.
+
+This vulnerability is only present in the nscd binary.
+
+There is no guarantee from the NSS callback API that the returned
+strings are all within the buffer. However, the netgroup cache code
+assumes that the NSS callback uses in-buffer strings and if it doesn't
+the buffer resizing logic could lead to potential memory corruption.
