+Subject: [PATCH] submodule-config: verify submodule names as paths
+
+Submodule "names" come from the untrusted .gitmodules file,
+but we blindly append them to $GIT_DIR/modules to create our
+on-disk repo paths. This means you can do bad things by
+putting "../" into the name (among other things).
+
+Let's sanity-check these names to avoid building a path that
+can be exploited. There are two main decisions:
+
+  1. What should the allowed syntax be?
+
+     It's tempting to reuse verify_path(), since submodule
+     names typically come from in-repo paths. But there are
+     two reasons not to:
+
+       a. It's technically more strict than what we need, as
+          we really care only about breaking out of the
+          $GIT_DIR/modules/ hierarchy.  E.g., having a
+          submodule named "foo/.git" isn't actually
+          dangerous, and it's possible that somebody has
+          manually given such a funny name.
+
+       b. Since we'll eventually use this checking logic in
+          fsck to prevent downstream repositories, it should
+          be consistent across platforms. Because
+          verify_path() relies on is_dir_sep(), it wouldn't
+          block "foo\..\bar" on a non-Windows machine.
+
+  2. Where should we enforce it? These days most of the
+     .gitmodules reads go through submodule-config.c, so
+     I've put it there in the reading step. That should
+     cover all of the C code.
+
+     We also construct the name for "git submodule add"
+     inside the git-submodule.sh script. This is probably
+     not a big deal for security since the name is coming
+     from the user anyway, but it would be polite to remind
+     them if the name they pick is invalid (and we need to
+     expose the name-checker to the shell anyway for our
+     test scripts).
+
+     This patch issues a warning when reading .gitmodules
+     and just ignores the related config entry completely.
+     This will generally end up producing a sensible error,
+     as it works the same as a .gitmodules file which is
+     missing a submodule entry (so "submodule update" will
+     barf, but "git clone --recurse-submodules" will print
+     an error but not abort the clone.
+
+     There is one minor oddity, which is that we print the
+     warning once per malformed config key (since that's how
+     the config subsystem gives us the entries). So in the
+     new test, for example, the user would see three
+     warnings. That's OK, since the intent is that this case
+     should never come up outside of malicious repositories
+     (and then it might even benefit the user to see the
+     message multiple times).
+
+Credit for finding this vulnerability and the proof of
+concept from which the test script was adapted goes to
+Etienne Stalmans.

+Subject: [PATCH] [perl #132063]: Heap buffer overflow
+
+The proximal cause is several instances in regexec.c of the code
+assuming that the input was valid UTF-8, whereas the input was too short
+for what the start byte claimed it would be.
+
+I grepped through the core for any other similar uses, and did not find
+any.

+Subject: [PATCH] (perl #132063) we should no longer warn for this code
+
+The first patch for 132063 prevented the buffer read overflow when
+dumping the warning but didn't fix the underlying problem.
+
+The next change treats the supplied buffer correctly, preventing the
+non-UTF-8 SV from being treated as UTF-8, preventing the warning.

+Subject: [PATCH] (perl #131844) fix various space calculation issues in
+ pp_pack.c
+
+- for the originally reported case, if the start/cur pointer is in the
+  top 75% of the address space the add (cur) + glen addition would
+  overflow, resulting in the condition failing incorrectly.
+
+- the addition of the existing space used to the space needed could
+  overflow, resulting in too small an allocation and a buffer overflow.
+
+- the scaling for UTF8 could overflow.
+
+- the multiply to calculate the space needed for many items could
+  overflow.
+
+For the first case, do a space calculation without making new pointers.
+
+For the other cases, detect the overflow and croak if there's an
+overflow.
+
+Originally this used Size_t_MAX as the maximum size of a memory
+allocation, but for -DDEBUGGING builds realloc() throws a panic for
+allocations over half the address space in size, changing the error
+reported for the allocation.
+
+For non-DEBUGGING builds the Size_t_MAX limit has the small chance
+of finding a system that has 3GB of contiguous space available, and
+allocating that space, which could be a denial of servce in some cases.
+
+Unfortunately changing the limit to half the address space means that
+the exact case with the original issue can no longer occur, so the
+test is no longer testing against the address + length issue that
+caused the original problem, since the allocation is failing earlier.
+
+One option would be to change the test so the size request by pack is
+just under 2GB, but this has a higher (but still low) probability that
+the system has the address space available, and will actually try to
+allocate the memory, so let's not do that.

+Subject: [PATCH] bpo-31530: fix crash when multiple threads iterate over a
+ file, round 2 (#5060)
+
+Multiple threads iterating over a file can corrupt the file's internal readahead
+buffer resulting in crashes. To fix this, cache buffer state thread-locally for
+the duration of a file_iternext call and only update the file's internal state
+after reading completes.
+
+No attempt is made to define or provide "reasonable" semantics for iterating
+over a file on multiple threads. (Non-crashing) races are still
+present. Duplicated, corrupt, and missing data will happen.
+
+This was originally fixed by 6401e5671781eb217ee1afb4603cc0d1b0367ae6, which
+raised an exception from seek() and next() when concurrent operations were
+detected. Alas, this simpler solution breaks legitimate use cases such as
+capturing the standard streams when multiple threads are logging.

+The multiboot spec (https://www.gnu.org/software/grub/manual/multiboot/),

+A zero bss_end_addr signifies there is no .bss section.
