-Subject: PATCH sed: handle very long execution lines (tiny change)
-
-If sed is called with an excessively long execution line, then it is
-prone to an out of bounds memory access.
-
-The problem is that the length of the execution line, which is a
-size_t, is temporarily stored in an int. This means that on systems
-which have a 64 bit size_t and a 32 bit int (e.g. linux amd64) an
-execution line which exceeds 2 GB will overflow int. If it is just
-slightly larger than 2 GB, the negative int value is used as an
-array index to finish the execution line string with '\0' which
-therefore triggers the out of bounds access.
-
-This problem is probably never triggered in reality, but can be
-provoked like this (given that 'e' support is compiled in):
-
-$ dd if=/dev/zero bs=1M count=2049 | tr '\0' e > e-command.txt
-$ sed -f e-command.txt /etc/fstab
-Segmentation fault (core dumped)
-
-Also adjust another int/size_t conversion, even though it is a
-purely cosmetic change, because it can never be larger than 4096.
-
-* sed/execute.c (execute_program) case 'e': Declare cmd_length
-to be of type size_t, not int.  Likewise for "n" just below.
-* NEWS (Bug fixes): Mention it.

-Subject: PATCH sed: handle very long input lines with R (tiny change)
-
-It is possible to trigger an out of bounds memory access when
-using the sed command R with an input file containing very long
-lines.
-
-The problem is that the line length of parsed file is returned as
-a size_t by ck_getdelim, but temporarily stored in an int and
-then converted back into a size_t. On systems like amd64, on which
-this problem can be triggered, size_t and int have different sizes.
-
-If the input line is longer than 2 GB (which is parseable on amd64
-or other 64 bit systems), this means that the temporarily stored
-int turns negative. Converting the negative int back into a size_t
-will lead to an excessively large size_t, as the conversion leads to
-a lot of leading 1 bits.
-
-Eventually ck_fwrite is called with this huge size_t which in turn
-will lead to an out of bounds access on amd64 systems -- after all
-the parsed text was just a bit above 2 GB, not near SIZE_MAX.
-
-You can trigger this issue with GNU sed on OpenBSD like this:
-
-$ dd if=/dev/zero bs=1M count=2049 | tr '\0' e > long.txt
-$ sed Rlong.txt /etc/fstab
-Segmentation fault (core dumped)
-
-I was unable to trigger the bug on a Linux system with glibc due to
-a bug in glibc's fwrite implementation -- it leads to a short write
-and sed treats that correctly as an error.
-
-* sed/execute.c (execute_program) case 'R': Declare result
-to be of type size_t, not int.
