+Description: fix multiple integer overflows in the XML_GetBuffer function
+ Multiple integer overflows in the XML_GetBuffer function in Expat through
+ 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products,
+ allow remote attackers to cause a denial of service (heap-based buffer

++     that apply (though RETURN and MERGE exist).  We make a distinction
++     between TRYAGAIN (recoverable) and TRYAGAIN' (not-recoverable).
++     A recoverable TRYAGAIN is almost always due to buffer size issues
++     and returns ERANGE in errno and the caller is expected to retry
++     with a larger buffer.
++
++     Lastly, you may be tempted to make significant changes to the
++     conditions in this code to bring about symmetry between responses.
++     Please don't change anything without due consideration for
++     expected application behaviour.  Some of the synthesized responses
++     aren't very well thought out and sometimes appear to imply that
++     IPv4 responses are always answer 1, and IPv6 responses are always
++     answer 2, but that's not true (see the implemetnation of send_dg
++     and send_vc to see response can arrive in any order, particlarly
++     for UDP). However, we expect it holds roughly enough of the time
++     that this code works, but certainly needs to be fixed to make this
++     a more robust implementation.

++         This ignores the state of the second answer and in fact
++         incorrectly sets errno and h_errno to that of the second
++	 answer.  However because the response is a success we ignore
++	 *errnop and *h_errnop (though that means you touched errno on
++         success).  We are being conservative here and returning the
++         likely IPv4 response in the first answer as a success.
++
++     [2] If the first response is a recoverable TRYAGAIN we return
++	 that instead of looking at the second response.  The
++	 expectation here is that we have failed to get an IPv4 response
++	 and should retry both queries.
++
++     [3] If the first response was not a SUCCESS and the second
++	 response is not NOTFOUND (had a SUCCESS, need to TRYAGAIN,
++	 or failed entirely e.g. TRYAGAIN' and UNAVAIL) then use the
++	 result from the second response, otherwise the first responses
++	 status is used.  Again we have some odd side-effects when the
++	 second response is NOTFOUND because we overwrite *errnop and
++	 *h_errnop that means that a first answer of NOTFOUND might see
++	 its *errnop and *h_errnop values altered.  Whether it matters
++	 in practice that a first response NOTFOUND has the wrong
++	 *errnop and *h_errnop is undecided.
++
++     [4] If the first response is UNAVAIL we return that instead of
++	 looking at the second response.  The expectation here is that
++	 it will have failed similarly e.g. configuration failure.
++
++     [5] Testing this code is complicated by the fact that truncated
++	 second response buffers might be returned as SUCCESS if the
++	 first answer is a SUCCESS.  To fix this we add symmetry to
++	 TRYAGAIN with the second response.  If the second response
++	 is a recoverable error we now return TRYAGIN even if the first
++	 response was SUCCESS.  */

++/* The send_vc function is responsible for sending a DNS query over TCP
++   to the nameserver numbered NS from the res_state STATP i.e.
++   EXT(statp).nssocks[ns].  The function supports sending both IPv4 and
++   IPv6 queries at the same serially on the same socket.
++
++   Please note that for TCP there is no way to disable sending both
++   queries, unlike UDP, which honours RES_SNGLKUP and RES_SNGLKUPREOP
++   and sends the queries serially and waits for the result after each
++   sent query.  This implemetnation should be corrected to honour these
++   options.
++
++   Please also note that for TCP we send both queries over the same
++   socket one after another.  This technically violates best practice
++   since the server is allowed to read the first query, respond, and
++   then close the socket (to service another client).  If the server
++   does this, then the remaining second query in the socket data buffer
++   will cause the server to send the client an RST which will arrive
++   asynchronously and the client's OS will likely tear down the socket
++   receive buffer resulting in a potentially short read and lost
++   response data.  This will force the client to retry the query again,
++   and this process may repeat until all servers and connection resets
++   are exhausted and then the query will fail.  It's not known if this
++   happens with any frequency in real DNS server implementations.  This
++   implementation should be corrected to use two sockets by default for
++   parallel queries.
++
++   The query stored in BUF of BUFLEN length is sent first followed by
++   the query stored in BUF2 of BUFLEN2 length.  Queries are sent
++   serially on the same socket.
++
++   Answers to the query are stored firstly in *ANSP up to a max of
++   *ANSSIZP bytes.  If more than *ANSSIZP bytes are needed and ANSCP
++   is non-NULL (to indicate that modifying the answer buffer is allowed)
++   then malloc is used to allocate a new response buffer and ANSCP and
++   ANSP will both point to the new buffer.  If more than *ANSSIZP bytes
++   are needed but ANSCP is NULL, then as much of the response as
++   possible is read into the buffer, but the results will be truncated.
++   When truncation happens because of a small answer buffer the DNS
++   packets header feild TC will bet set to 1, indicating a truncated
++   message and the rest of the socket data will be read and discarded.
++
++   Answers to the query are stored secondly in *ANSP2 up to a max of
++   *ANSSIZP2 bytes, with the actual response length stored in
++   *RESPLEN2.  If more than *ANSSIZP bytes are needed and ANSP2
++   is non-NULL (required for a second query) then malloc is used to
++   allocate a new response buffer, *ANSSIZP2 is set to the new buffer
++   size and *ANSP2_MALLOCED is set to 1.
++
++   The ANSP2_MALLOCED argument will eventually be removed as the
++   change in buffer pointer can be used to detect the buffer has
++   changed and that the caller should use free on the new buffer.
++
++   Note that the answers may arrive in any order from the server and
++   therefore the first and second answer buffers may not correspond to
++   the first and second queries.
++
++   It is not supported to call this function with a non-NULL ANSP2
++   but a NULL ANSCP.  Put another way, you can call send_vc with a
++   single unmodifiable buffer or two modifiable buffers, but no other
++   combination is supported.
++
++   It is the caller's responsibility to free the malloc allocated
++   buffers by detecting that the pointers have changed from their
++   original values i.e. *ANSCP or *ANSP2 has changed.
++
++   If errors are encountered then *TERRNO is set to an appropriate
++   errno value and a zero result is returned for a recoverable error,
++   and a less-than zero result is returned for a non-recoverable error.
++
++   If no errors are encountered then *TERRNO is left unmodified and
++   a the length of the first response in bytes is returned.  */

+Fix CVE-2016-1541 (buffer overflow zip_read_mac_metadata)
+
+Taken from upstream source repository:
+https://github.com/libarchive/libarchive/commit/d0331e8e5b05b475f20b1f3101fe1ad772d7e7e7
+
+When reading OS X metadata entries in Zip archives that were stored
+without compression, libarchive would use the uncompressed entry size
+to allocate a buffer but would use the compressed entry size to limit
+the amount of data copied into that buffer.  Since the compressed
+and uncompressed sizes are provided by data in the archive itself,
+an attacker could manipulate these values to write data beyond
+the end of the allocated buffer.
+
+This fix provides three new checks to guard against such
+manipulation and to make libarchive generally more robust when
+handling this type of entry:
+ 1. If an OS X metadata entry is stored without compression,
+    abort the entire archive if the compressed and uncompressed
+    data sizes do not match.
+ 2. When sanity-checking the size of an OS X metadata entry,
+    abort this entry if either the compressed or uncompressed
+    size is larger than 4MB.
+ 3. When copying data into the allocated buffer, check the copy
+    size against both the compressed entry size and uncompressed
+    entry size.

+    Use ustar format in the test_option_b test
+    
+    .. because the ustar archive does not store SELinux context.  As the default
+    format for bsdtar is "restricted pax" (trying to store xattrs and other
+    things by default), the test failed on Fedora because our files have by
+    default SELinux context set.  This results in additional data in tested

+Subject: [PATCH 3/3] Fix leaks in kadmin server stubs [CVE-2015-8631]
+
+In each kadmind server stub, initialize the client_name and
+server_name variables, and release them in the cleanup handler.  Many
+of the stubs will otherwise leak the client and server name if
+krb5_unparse_name() fails.  Also make sure to free the prime_arg
+variables in rename_principal_2_svc(), or we can leak the first one if
+unparsing the second one fails.  Discovered by Simo Sorce.
+
+CVE-2015-8631:
+
+In all versions of MIT krb5, an authenticated attacker can cause
+kadmind to leak memory by supplying a null principal name in a request
+which uses one.  Repeating these requests will eventually cause
+kadmind to exhaust all available memory.

+Subject: [PATCH] Check internal context on init context errors
+
+If the mechanism deletes the internal context handle on error, the
+mechglue must do the same with the union context, to avoid crashes if
+the application calls other functions with this invalid union context.

- 5.3.1-14ubuntu2
-
-Rapicorn uses isnan(...) and isinf(...) from cmath.h, however on KUbuntu 16.04
-it should use std::isnan(...) and std::isinf(...) instead. Patch below.
