+
+After processing the command-line yet arriving at the point where we are

+no sense since we never put anything into the allocated argv.
+
+The solution is to simply return that we've successfully processed the
+arguments but that argc == 0, and also ensure that argv is NULL when
+we're not allocating anything in it.
+
+There are only 2 callers of this function, and both are handling a zero
+value in argc assuming nothing is allocated in argv.

+Subject: [PATCH] efi: Fix some malformed device path arithmetic errors
+
+Several places we take the length of a device path and subtract 4 from
+it, without ever checking that it's >= 4. There are also cases where
+this kind of malformation will result in unpredictable iteration,
+including treating the length from one dp node as the type in the next
+node. These are all errors, no matter where the data comes from.
+
+This patch adds a checking macro, GRUB_EFI_DEVICE_PATH_VALID(), which
+can be used in several places, and makes GRUB_EFI_NEXT_DEVICE_PATH()
+return NULL and GRUB_EFI_END_ENTIRE_DEVICE_PATH() evaluate as true when
+the length is too small. Additionally, it makes several places in the
+code check for and return errors in these cases.

+Subject: [PATCH] kern/efi/mm: Fix possible NULL pointer dereference
+
+The model of grub_efi_get_memory_map() is that if memory_map is NULL,
+then the purpose is to discover how much memory should be allocated to
+it for the subsequent call.
+
+The problem here is that with grub_efi_is_finished set to 1, there is no
+check at all that the function is being called with a non-NULL memory_map.
+
+While this MAY be true, we shouldn't assume it.
+
+The solution to this is to behave as expected, and if memory_map is NULL,
+then don't try to use it and allow memory_map_size to be filled in, and
+return 0 as is done later in the code if the buffer is too small (or NULL).
+
+Additionally, drop unneeded ret = 1.

+Subject: [PATCH] gnulib/regexec: Resolve unused variable
+
+This is a really minor issue where a variable is being assigned to but
+not checked before it is overwritten again.
+
+The reason for this issue is that we are not building with DEBUG set and
+this in turn means that the assert() that reads the value of the
+variable match_last is being processed out.
+
+The solution, move the assignment to match_last in to an ifdef DEBUG too.

+Subject: [PATCH] gnulib/regexec: Fix possible null-dereference
+
+It appears to be possible that the mctx->state_log field may be NULL,
+and the name of this function, clean_state_log_if_needed(), suggests
+that it should be checking that it is valid to be cleaned before
+assuming that it does.

+The problem here is that the memory allocated to the variable lv is not

+
+As we can already see at line 342, which correctly frees lv before going
+to fail2, we should also be doing that at these earlier jumps to fail2.

+HFS+ documentation suggests that the maximum filename and volume name is
+255 Unicode characters in length.
+
+So, when converting from big-endian to little-endian, we should ensure

+Subject: [PATCH] zfs: Fix possible negative shift operation
+
+While it is possible for the return value from zfs_log2() to be zero
+(0), it is quite unlikely, given that the previous assignment to blksz
+is shifted up by SPA_MINBLOCKSHIFT (9) before 9 is subtracted at the
+assignment to epbs.
+
+But, while unlikely during a normal operation, it may be that a carefully
+crafted ZFS filesystem could result in a zero (0) value to the
+dn_datalbkszsec field, which means that the shift left does nothing
+and assigns zero (0) to blksz, resulting in a negative epbs value.

+Subject: [PATCH] zfs: Fix resource leaks while constructing path
+
+There are several exit points in dnode_get_path() that are causing possible
+memory leaks.
+
+In the while(1) the correct exit mechanism should not be to do a direct return,
+but to instead break out of the loop, setting err first if it is not already set.
+
+The reason behind this is that the dnode_path is a linked list, and while doing
+through this loop, it is being allocated and built up - the only way to
+correctly unravel it is to traverse it, which is what is being done at the end
+of the function outside of the loop.
+
+Several of the existing exit points correctly did a break, but not all so this
+change makes that more consistent and should resolve the leaking of memory as
+found by Coverity.

+
+The node structure reference is being allocated but not freed if it
+reaches the end of the function. If any of the hooks had returned
+a non-zero value, then node would have been copied in to the context
+reference, but otherwise node is not stored and should be freed.
+
+Similarly, the call to grub_affs_create_node() replaces the allocated
+memory in node with a newly allocated structure, leaking the existing
+memory pointed by node.
+
+Finally, when dir->parent is set, then we again replace node with newly
+allocated memory, which seems unnecessary when we copy in the values
+from dir->parent immediately after.

+Subject: [PATCH] libgcrypt/mpi: Fix possible unintended sign extension
+
+The array of unsigned char gets promoted to a signed 32-bit int before
+it is finally promoted to a size_t. There is the possibility that this
+may result in the signed-bit being set for the intermediate signed
+32-bit int. We should ensure that the promotion is to the correct type
+before we bitwise-OR the values.

+The code in the next block suggests that it is possible for .set to be

+
+This code assumes that it is never NULL, yet later is testing if it is
+NULL - that is inconsistent.
+
+So we should check first if .arg is not NULL, and remove this check that
+is being flagged by Coverity since it is no longer required.

+Subject: [PATCH] util/glue-efi: Fix incorrect use of a possibly negative value
+
+It is possible for the ftell() function to return a negative value,
+although it is fairly unlikely here, we should be checking for
+a negative value before we assign it to an unsigned value.

+
+"$#" represents the number of arguments to a function. It is only

+if we attempt to evaluate "$#" outside a function scope, "scope" will
+be NULL and we will crash with a NULL pointer dereference.
+
+Do not attempt to count arguments for "$#" if "scope" is NULL. This
+will result in "$#" being interpreted as an empty string if evaluated
+outside a function scope.

+Subject: [PATCH] dl: Only allow unloading modules that are not dependencies
+
+When a module is attempted to be removed its reference counter is always
+decremented. This means that repeated rmmod invocations will cause the
+module to be unloaded even if another module depends on it.
+
+This may lead to a use-after-free scenario allowing an attacker to execute
+arbitrary code and by-pass the UEFI Secure Boot protection.
+
+While being there, add the extern keyword to some function declarations in
+that header file.

+Subject: dnsproxy: Avoid 100 % busy loop in TCP server case
+
+Once the TCP socket is connected and until the remote server is
+responding (if ever) ConnMan executes a 100 % CPU loop, since
+the connected socket will always be writable (G_IO_OUT).
+
+To fix this, modify the watch after the connection is established to

+Subject: [PATCH 3/4] SAE: Derive the y coordinate for PWE with own
+ implementation
+
+The crypto_ec_point_solve_y_coord() wrapper function might not use
+constant time operations in the crypto library and as such, could leak
+side channel information about the password that is used to generate the
+PWE in the hunting and pecking loop. As such, calculate the two possible
+y coordinate values and pick the correct one to use with constant time
+selection.

+Subject: [PATCH 4/4] EAP-pwd: Derive the y coordinate for PWE with own
+ implementation
+
+The crypto_ec_point_solve_y_coord() wrapper function might not use
+constant time operations in the crypto library and as such, could leak
+side channel information about the password that is used to generate the
+PWE in the hunting and pecking loop. As such, calculate the two possible
+y coordinate values and pick the correct one to use with constant time
+selection.
