<define-tag moreinfo>
<p>여러 연구자가 인텔 프로세서 취약점을 발견했는데,
공격자가 임의 주소에서 메모리를 읽어서 권한없는 프로세스를 제어할 수 있게 되며,
커널과 시스템에서 돌아가는 모든 다른 프로세서를 포함합니다.
</p>
<p>이 특정 공격은 Meltdown 이라 이름 지어졌으며 x86-64 아키텍처 리눅스 커널에서
Kernel Page Table Isolation 이라 불리는 패치 세트로 해결되었으며,
This specific attack has been named Meltdown and is addressed in the Linux
kernel for the Intel x86-64 architecture by a patch set named Kernel Page Table
Isolation, enforcing a near complete separation of the kernel and userspace
address maps and preventing the attack. This solution might have a performance
impact, and can be disabled at boot time by passing <code>pti=off</code> to the
kernel command line.</p>
<p>We also identified a regression for ancient userspaces using the vsyscall
interface, for example chroot and containers using (e)glibc 2.13 and older,
including those based on Debian 7 or RHEL/CentOS 6. This regression will be
fixed in a later update.</p>
<p>The other vulnerabilities (named Spectre) published at the same time are not
addressed in this update and will be fixed in a later update.</p>
<p>For the oldstable distribution (jessie), this problem will be fixed in a
separate update.</p>
<p>For the stable distribution (stretch), this problem has been fixed in
version 4.9.65-3+deb9u2.</p>
<p>We recommend that you upgrade your linux packages.</p>
