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
netgroup response to the cache, the client request can result in a null
pointer dereference. 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: 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.
