CVE ID         : CVE-2017-10686 CVE-2017-11111

CVE-2017-10686
      In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use
      after free vulnerabilities in the tool nasm. The related heap is
      allocated in the token() function and freed in the detoken()
      function (called by pp_getline()) - it is used again at multiple
      positions later that could cause multiple damages. For example,
      it causes a corrupted double-linked list in detoken(), a double
      free or corruption in delete_Token(), and an out-of-bounds write
      in detoken(). It has a high possibility to lead to a remote code
      execution attack.

CVE-2017-11111
      In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote
      attackers to cause a denial of service (heap-based buffer
      overflow and application crash) or possibly have unspecified
      other impact via a crafted file.


For Debian 7 "Wheezy", these problems have been fixed in version
2.10.01-1+deb7u1.

We recommend that you upgrade your nasm packages.
