+Subject: [PATCH] realpath: Set errno to ENAMETOOLONG for result larger than
+ PATH_MAX [BZ #28770]
+
+realpath returns an allocated string when the result exceeds PATH_MAX,
+which is unexpected when its second argument is not NULL. This results
+in the second argument (resolved) being uninitialized and also results
+in a memory leak since the caller expects resolved to be the same as the
+returned value.
+
+Return NULL and set errno to ENAMETOOLONG if the result exceeds
+PATH_MAX. This fixes [BZ #28770], which is CVE-2021-3998.

+Subject: [PATCH] getcwd: Set errno to ERANGE for size == 1 (CVE-2021-3999)
+
+No valid path returned by getcwd would fit into 1 byte, so reject the
+size early and return NULL with errno set to ERANGE. This change is
+prompted by CVE-2021-3999, which describes a single byte buffer
+underflow and overflow when all of the following conditions are met:
+
+- The buffer size (i.e. the second argument of getcwd) is 1 byte
+- The current working directory is too long
+- '/' is also mounted on the current working directory
+
+Sequence of events:
+
+- In sysdeps/unix/sysv/linux/getcwd.c, the syscall returns ENAMETOOLONG
+ because the linux kernel checks for name length before it checks
+ buffer size
+
+- The code falls back to the generic getcwd in sysdeps/posix
+
+- In the generic func, the buf[0] is set to '\0' on line 250
+
+- this while loop on line 262 is bypassed:
+
+ while (!(thisdev == rootdev && thisino == rootino))
+
+ since the rootfs (/) is bind mounted onto the directory and the flow
+ goes on to line 449, where it puts a '/' in the byte before the
+ buffer.
+
+- Finally on line 458, it moves 2 bytes (the underflowed byte and the
+ '\0') to the buf[0] and buf[1], resulting in a 1 byte buffer overflow.
+
+- buf is returned on line 469 and errno is not set.
+
+This resolves BZ #28769.

+Subject: [PATCH] gconv: Do not emit spurious NUL character in ISO-2022-JP-3
+ (bug 28524)
+
+Bugfix 27256 has introduced another issue:
+In conversion from ISO-2022-JP-3 encoding, it is possible
+to force iconv to emit extra NUL character on internal state reset.
+To do this, it is sufficient to feed iconv with escape sequence
+which switches active character set.
+The simplified check 'data->__statep->__count != ASCII_set'
+introduced by the aforementioned bugfix picks that case and
+behaves as if '\0' character has been queued thus emitting it.
+
+To eliminate this issue, these steps are taken:
+* Restore original condition
+'(data->__statep->__count & ~7) != ASCII_set'.
+It is necessary since bits 0-2 may contain
+number of buffered input characters.
+* Check that queued character is not NUL.
+Similar step is taken for main conversion loop.
+
+Bundled test case follows following logic:
+* Try to convert ISO-2022-JP-3 escape sequence
+switching active character set
+* Reset internal state by providing NULL as input buffer
+* Ensure that nothing has been converted.
