bind: update to 9.11.36

Security Fixes

The lame-ttl option controls how long named caches certain types of
broken responses from authoritative servers (see the security advisory
for details). This caching mechanism could be abused by an attacker to
significantly degrade resolver performance. The vulnerability has been
mitigated by changing the default value of lame-ttl to 0 and overriding
any explicitly set value with 0, effectively disabling this mechanism
altogether. ISC's testing has determined that doing that has a
negligible impact on resolver performance while also preventing abuse.
Administrators may observe more traffic towards servers issuing certain
types of broken responses than in previous BIND 9 releases, depending on
client query patterns. (CVE-2021-25219)

ISC would like to thank Kishore Kumar Kothapalli of Infoblox for
bringing this vulnerability to our attention. [GL #2899]

+
+After processing the command-line yet arriving at the point where we are
+setting argv, we are allocating memory, even if argc == 0, which makes
+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.

+
+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.

+
+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
+true but .arg may still be NULL.
+
+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.

+The return value of ftell() may be negative (-1) on error. While it is

+Subject: [PATCH] kern: Add lockdown support
+
+When the GRUB starts on a secure boot platform, some commands can be
+used to subvert the protections provided by the verification mechanism and
+could lead to booting untrusted system.
+
+To prevent that situation, allow GRUB to be locked down. That way the code
+may check if GRUB has been locked down and further restrict the commands
+that are registered or what subset of their functionality could be used.
+
+The lockdown support adds the following components:
+
+* The grub_lockdown() function which can be used to lockdown GRUB if,
+  e.g., UEFI Secure Boot is enabled.
+
+* The grub_is_lockdown() function which can be used to check if the GRUB
+  was locked down.
+
+* A verifier that flags OS kernels, the GRUB modules, Device Trees and ACPI
+  tables as GRUB_VERIFY_FLAGS_DEFER_AUTH to defer verification to other
+  verifiers. These files are only successfully verified if another registered
+  verifier returns success. Otherwise, the whole verification process fails.
+
+  For example, PE/COFF binaries verification can be done by the shim_lock
+  verifier which validates the signatures using the shim_lock protocol.
+  However, the verification is not deferred directly to the shim_lock verifier.
+  The shim_lock verifier is hooked into the verification process instead.
+
+* A set of grub_{command,extcmd}_lockdown functions that can be used by
+  code registering command handlers, to only register unsafe commands if
+  the GRUB has not been locked down.

++
++The GRUB can be locked down, which is a restricted mode where some operations
++are not allowed. For instance, some commands cannot be used when the GRUB is
++locked down.
++
++The function
++@code{grub_lockdown()} is used to lockdown GRUB and the function
++@code{grub_is_lockdown()} function can be used to check whether lockdown is
++enabled or not. When enabled, the function returns @samp{GRUB_LOCKDOWN_ENABLED}
++and @samp{GRUB_LOCKDOWN_DISABLED} when is not enabled.
++
++The following functions can be used to register the commands that can only be
++used when lockdown is disabled:
++
++@itemize
++
++@item @code{grub_cmd_lockdown()} registers command which should not run when the
++GRUB is in lockdown mode.
++
++@item @code{grub_cmd_lockdown()} registers extended command which should not run
++when the GRUB is in lockdown mode.

+Subject: [PATCH] efi: Use grub_is_lockdown() instead of hardcoding a disabled
+ modules list
+
+Now the GRUB can check if it has been locked down and this can be used to
+prevent executing commands that can be utilized to circumvent the UEFI
+Secure Boot mechanisms. So, instead of hardcoding a list of modules that
+have to be disabled, prevent the usage of commands that can be dangerous.
+
+This not only allows the commands to be disabled on other platforms, but
+also properly separate the concerns. Since the shim_lock verifier logic
+should be only about preventing to run untrusted binaries and not about
+defining these kind of policies.

+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: [PATCH] commands: Restrict commands that can load BIOS or DT blobs
+ when locked down
+
+There are some more commands that should be restricted when the GRUB is
+locked down. Following is the list of commands and reasons to restrict:
+
+  * fakebios:   creates BIOS-like structures for backward compatibility with
+                existing OSes. This should not be allowed when locked down.
+
+  * loadbios:   reads a BIOS dump from storage and loads it. This action
+                should not be allowed when locked down.
+
+  * devicetree: loads a Device Tree blob and passes it to the OS. It replaces
+                any Device Tree provided by the firmware. This also should
+                not be allowed when locked down.
