<p>여러 취약점을 리눅스 커널에서 발견, 권한 상승, 서비스 거부 또는 정보 유출을 일으킬 수 있습니다.</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-3846">CVE-2019-3846</a>,
<a href="https://security-tracker.debian.org/tracker/CVE-2019-10126">CVE-2019-10126</a>
<p>huangwen reported multiple buffer overflows in the Marvell wifi
(mwifiex) driver, which a local user could use to cause denial of
service or the execution of arbitrary code.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-5489">CVE-2019-5489</a>
<p>Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael Schwarz, Ari
Trachtenberg, Jason Hennessey, Alex Ionescu, and Anders Fogh
discovered that local users could use the mincore() system call to
obtain sensitive information from other processes that access the
same memory-mapped file.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-9500">CVE-2019-9500</a>,
<a href="https://security-tracker.debian.org/tracker/CVE-2019-9503">CVE-2019-9503</a>
<p>Hugues Anguelkov discovered a buffer overflow and missing access
validation in the Broadcom FullMAC wifi driver (brcmfmac), which a
attacker on the same wifi network could use to cause denial of
service or the execution of arbitrary code.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11477">CVE-2019-11477</a>
<p>Jonathan Looney reported that a specially crafted sequence of TCP
selective acknowledgements (SACKs) allows a remotely triggerable
kernel panic.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11478">CVE-2019-11478</a>
<p>Jonathan Looney reported that a specially crafted sequence of TCP
selective acknowledgements (SACKs) will fragment the TCP
retransmission queue, allowing an attacker to cause excessive
resource usage.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11479">CVE-2019-11479</a>
<p>Jonathan Looney reported that an attacker could force the Linux
kernel to segment its responses into multiple TCP segments, each of
which contains only 8 bytes of data, drastically increasing the
bandwidth required to deliver the same amount of data.</p>
<p>This update introduces a new sysctl value to control the minimal MSS
(net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard coded value of 48. We recommend raising this to 536 unless you know
that your network requires a lower value.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11486">CVE-2019-11486</a>
<p>Jann Horn of Google reported numerous race conditions in the
Siemens R3964 line discipline. A local user could use these to
cause unspecified security impact. This module has therefore been
disabled.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11599">CVE-2019-11599</a>
<p>Jann Horn of Google reported a race condition in the core dump
implementation which could lead to a use-after-free. A local
user could use this to read sensitive information, to cause a
denial of service (memory corruption), or for privilege
escalation.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11815">CVE-2019-11815</a>
<p>It was discovered that a use-after-free in the Reliable Datagram
Sockets protocol could result in denial of service and potentially
privilege escalation. This protocol module (rds) is not auto loaded on Debian systems, so this issue only affects systems where
it is explicitly loaded.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11833">CVE-2019-11833</a>
<p>It was discovered that the ext4 filesystem implementation writes
uninitialised data from kernel memory to new extent blocks. A
local user able to write to an ext4 filesystem and then read the
filesystem image, for example using a removable drive, might be
able to use this to obtain sensitive information.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-11884">CVE-2019-11884</a>
<p>It was discovered that the Bluetooth HIDP implementation did not
ensure that new connection names were null-terminated. A local
user with CAP_NET_ADMIN capability might be able to use this to
obtain sensitive information from the kernel stack.</p></li>
</ul>
<p>안정 배포(stretch)에서, 이 문제를 버전 4.9.168-1+deb9u3에서 수정했습니다.</p>
<p>linux 패키지 업그레이드 권합니다.</p>
