CVE-2017-12196 – undertow: Client can use bogus uri in Digest authentication
https://notcve.org/view.php?id=CVE-2017-12196
undertow before versions 1.4.18.SP1, 2.0.2.Final, 1.4.24.Final was found vulnerable when using Digest authentication, the server does not ensure that the value of URI in the Authorization header matches the URI in HTTP request line. This allows the attacker to cause a MITM attack and access the desired content on the server. Se ha descubierto que undertow, en sus versiones 1.4.18.SP1, 2.0.2.Final y 1.4.24.Final, es vulnerable al usar la autenticación Digest, ya que el servidor no garantiza que el valor del URI en la cabecera Authorization coincida con el URIb en la línea de petición HTTP. Esto permite que el atacante provoque un ataque Man-in-the-Middle (MitM) y acceda al contenido que desee en el servidor. It was discovered that when using Digest authentication, the server does not ensure that the value of the URI in the authorization header matches the URI in the HTTP request line. • https://access.redhat.com/errata/RHSA-2018:0478 https://access.redhat.com/errata/RHSA-2018:0479 https://access.redhat.com/errata/RHSA-2018:0480 https://access.redhat.com/errata/RHSA-2018:0481 https://access.redhat.com/errata/RHSA-2018:1525 https://access.redhat.com/errata/RHSA-2018:2405 https://access.redhat.com/errata/RHSA-2018:3768 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12196 https://issues.jboss.org/browse/UNDERTOW-1190 https://access.redhat.com/sec • CWE-287: Improper Authentication CWE-863: Incorrect Authorization •

CVE-2017-15119 – qemu: DoS via large option request
https://notcve.org/view.php?id=CVE-2017-15119
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.
