Debian DLA-1041-1 : nasm security update

high Nessus Plugin ID 102039

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected nasm package.
