[SECURITY] [DLA 1041-1] nasm security update
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Package : nasm
Version : 2.10.01-1+deb7u1
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.
