Subject: zgrep: avoid exploit via multi-newline file names
* zgrep.in: The issue with the old code is that with multiple
newlines, the N-command will read the second line of input,
then the s-commands will be skipped because it's not the end
of the file yet, then a new sed cycle starts and the pattern
space is printed and emptied. So only the last line or two get
escaped. This patch makes sed read all lines into the pattern
space and then do the escaping.
This vulnerability was discovered by:
cleemy desu wayo working with Trend Micro Zero Day Initiative

Subject: zgrep: add NEWS and tests for this exploitable bug
* tests/zgrep-abuse: New file, based on PoC by cleemy desu wayo.
* tests/Makefile.am (TESTS): Add it.
* NEWS: Mention the exploit.
The bug appears to have been present since the beginning.

Subject: zgrep: port to POSIX sed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* zgrep.in (res): When escaping the file name do not rely on GNU
sed’s extension to POSIX with respect to s/.../\n/. Instead, use
features that should also work with AIX and/or Solaris sed. This is
simpler anyway, and would have prevented the recently-fixed bug.
