** Patch added: "libytnef-lp1666884-zesty.debdiff"
   https://bugs.launchpad.net/ubuntu/+source/libytnef/+bug/1666884/+attachment/4882632/+files/libytnef-lp1666884-zesty.debdiff

** CVE added: http://www.cve.mitre.org/cgi-
bin/cvename.cgi?name=2017-9058

** Description changed:

  http://www.openwall.com/lists/oss-security/2017/02/15/4
  
  https://github.com/Yeraze/ytnef/pull/27/files
  
  Upstream calls this X41-2017-002 but a bunch of CVEs have been assigned too.
  https://security-tracker.debian.org/tracker/source-package/libytnef
  
  Fixed in zesty. I'd like to copy the Debian stable security patches when
  it's released there.
  
  Quoting from the oss-security post…
  
  Summary and Impact
  ------------------
  Multiple Heap Overflows, out of bound writes and reads, NULL pointer
  dereferences and infinite loops have been discovered in ytnef 1.9 an
  earlier.
  These could be exploited by tricking a user into opening a malicious
  winmail.dat file.
  
  Product Description
  -------------------
  ytnef offers a library and utilities to extract the files from winmail.dat
  files. winmail.dat files are send by Microsoft Outlook when forwarding files
  via e-mail. The vendor was very responsive in providing a patched version.
  
  Analysis
  --------
  Due to the big amount of issues found no detailed analysis is given here.
  Almost all allocations were unchecked and out of bounds checks rarely
  performed in the code.
  
  In total 9 patches were generated for the following issues:
  
  1. Null Pointer Deref / calloc return value not checked
  2. Infinite Loop / DoS
  3. Buffer Overflow in version field
  4. Out of Bound Reads
  5. Integer Overflow
  6. Invalid Write and Integer Overflow
  7. Out of Bounds read
  8. Out of Bounds read and write
  9. Directory Traversal using the filename
+ 
+ Other Info
+ ----------
+ Zesty already got these fixes synced from Debian. Trusty got these fixes earlier in May since it was still in main. Recently, there's one more CVE, 2017-9058 so I've supplied debdiffs for trusty and zesty for that issue, copied from Debian's 1.9.2-2 package (which will autosync to artful). For xenial and yakkety, I also added the patches that were applied to trusty.
