https://notcve.org/view.php?id=CVE-2018-11763
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol. En Apache HTTP Server, de la versión 2.4.17 a la 2.4.34, mediante el envío continuo de tramas SETTINGS grandes, un cliente puede ocupar una conexión, hilo del servidor y tiempo de CPU sin que se active ningún agotamiento del tiempo de conexión. Esto solo afecta a las conexiones HTTP/2. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00056.html http://www.securityfocus.com/bid/105414 http://www.securitytracker.com/id/1041713 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7f • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-14634
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable. Se ha encontrado un error de desbordamiento de enteros en la función create_elf_tables() del kernel de Linux. Un usuario local sin privilegios con acceso al binario SUID (o a otro privilegiado) podría emplear este error para escalar sus privilegios en el sistema. • https://www.exploit-db.com/exploits/45516 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/105407 https://access.redhat.com/errata/RHSA-2018:2748 https://access.redhat.com/errata/RHSA-2018:2763 https://access.redhat.com/errata/RHSA-2018:2846 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018:2925 https://access.redhat.com/errata/RHSA-2018:2933 https://access.redhat.com/errata/RHSA- • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2018-12385
A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. This issue also triggers a non-exploitable startup crash for users switching between the Nightly and Release versions of Firefox if the same profile is used. This vulnerability affects Thunderbird < 60.2.1, Firefox ESR < 60.2.1, and Firefox < 62.0.2. Un cierre inesperado potencialmente explotable en TransportSecurityInfo empleado para SSL puede desencadenarse por los datos almacenados en la caché local en el directorio de perfil del usuario. • http://www.securityfocus.com/bid/105380 http://www.securitytracker.com/id/1041700 http://www.securitytracker.com/id/1041701 https://access.redhat.com/errata/RHSA-2018:2834 https://access.redhat.com/errata/RHSA-2018:2835 https://access.redhat.com/errata/RHSA-2018:3403 https://access.redhat.com/errata/RHSA-2018:3458 https://bugzilla.mozilla.org/show_bug.cgi?id=1490585 https://lists.debian.org/debian-lts-announce/2018/11/msg00011.html https://security.gentoo.org/glsa/201810- • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2017-15705 – spamassassin: Certain unclosed tags in crafted emails allow for scan timeouts and result in denial of service
https://notcve.org/view.php?id=CVE-2017-15705
A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html http://www.securityfocus.com/bid/105347 https://access.redhat.com/errata/RHSA-2018:2916 https://lists.apache.org/thread.html/7f6a16bc0fd0fd5e67c7fd95bd655069a2ac7d1f88e42d3c853e601c%40%3Cannounce.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00016.html https://security.gentoo.org/glsa/201812-07 https://usn.ubuntu.com/3811-1 https://usn.ubuntu.com/3811-2 https://access.redhat.com/security/cve/CVE& • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
