-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: 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.
