CVE-2019-9514 – Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9514
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio. El atacante abre una serie de secuencias y envía una solicitud no válida sobre cada secuencia que debería solicitar una secuencia de tramas RST_STREAM del par. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-3870
https://notcve.org/view.php?id=CVE-2019-3870
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3870 https://bugzilla.samba.org/show_bug.cgi?id=13834 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6354GALK73CZWQKFUG7AWB6EIEGFMF62 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTJVFA3RZ6G2IZDTVKLHRMX6QBYA4GPA https://support.f5.com/csp/article/K20804356 https://www.samba.org/samba/security/CVE-2019-3870.html https://www.synology.com/security/advisory/Synology_SA_19 • CWE-276: Incorrect Default Permissions •
CVE-2018-1160 – Netatalk 3.1.12 - Authentication Bypass (PoC)
https://notcve.org/view.php?id=CVE-2018-1160
Netatalk before 3.1.12 is vulnerable to an out of bounds write in dsi_opensess.c. This is due to lack of bounds checking on attacker controlled data. A remote unauthenticated attacker can leverage this vulnerability to achieve arbitrary code execution. Netatalk, en versiones anteriores a la 3.1.12, es vulnerable a una escritura fuera de límites en dsi_opensess.c. Esto se debe a la falta de comprobación de límites de los datos controlados por el atacante. • https://www.exploit-db.com/exploits/46048 https://www.exploit-db.com/exploits/46034 https://www.exploit-db.com/exploits/46675 https://github.com/SachinThanushka/CVE-2018-1160 http://netatalk.sourceforge.net/3.1/ReleaseNotes3.1.12.html http://packetstormsecurity.com/files/152440/QNAP-Netatalk-Authentication-Bypass.html http://www.securityfocus.com/bid/106301 https://attachments.samba.org/attachment.cgi?id=14735 https://github.com/tenable/poc/tree/master/netatalk/cve_2018_1160 https:/ • CWE-787: Out-of-bounds Write •
CVE-2018-7185
https://notcve.org/view.php?id=CVE-2018-7185
The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association. El motor de protocolo en ntp, en versiones 4.2.6 anteriores a la 4.2.8p11, permite que atacantes remotos provoquen una denegación de servicio (interrupción) mediante el envío continuado de un paquete con una marca de tiempo zero-origin y la dirección IP de origen "del otro lado" de una asociación intercalada que provoca que el ntpd de la víctima restablezca su asociación. • http://packetstormsecurity.com/files/146631/Slackware-Security-Advisory-ntp-Updates.html http://support.ntp.org/bin/view/Main/NtpBug3454 http://www.securityfocus.com/archive/1/541824/100/0/threaded http://www.securityfocus.com/bid/103339 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:02.ntp.asc https://security.gentoo.org/glsa/201805-12 https://security.netapp.com/advisory/ntap-20180626-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03962en •
CVE-2018-7184
https://notcve.org/view.php?id=CVE-2018-7184
ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. ntpd en ntp, en versiones 4.2.8p4 anteriores a la 4.2.8p11, envía paquetes malos antes de actualizar la marca de tiempo "received". Esto permite que atacantes remotos provoquen una denegación de servicio (interrupción) mediante el envío de un paquete con una marca de tiempo zero-origin que provoca que la asociación se restablezca y establezca el contenido del paquete como la marca de tiempo más reciente. Este problema es el resultado de una solución incompleta para CVE-2015-7704. • http://packetstormsecurity.com/files/146631/Slackware-Security-Advisory-ntp-Updates.html http://support.ntp.org/bin/view/Main/NtpBug3453 http://www.securityfocus.com/archive/1/541824/100/0/threaded http://www.securityfocus.com/bid/103192 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:02.ntp.asc https://security.gentoo.org/glsa/201805-12 https://security.netapp.com/advisory/ntap-20180626-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03962en •
