CVE-2018-14634 – Linux Kernel 2.6.x / 3.10.x / 4.14.x (RedHat / Debian / CentOS) (x64) - 'Mutagen Astronomy' Local Privilege Escalation
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 •
CVE-2018-11763 – Apache2 mod_http2 header Denial of Service Vulnerability
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 •
CVE-2018-14642 – undertow: Infoleak in some circumstances where Undertow can serve data from a random buffer
https://notcve.org/view.php?id=CVE-2018-14642
An information leak vulnerability was found in Undertow. If all headers are not written out in the first write() call then the code that handles flushing the buffer will always write out the full contents of the writevBuffer buffer, which may contain data from previous requests. Se ha encontrado una vulnerabilidad de fuga de información en Undertow. Si no están escritas todas las cabeceras en la primera llamada write(), el código que maneja las escrituras al búfer siempre escribirá el contenido completo del búfer writevBuffer, que podría contener datos de peticiones anteriores. • https://access.redhat.com/errata/RHSA-2019:0362 https://access.redhat.com/errata/RHSA-2019:0364 https://access.redhat.com/errata/RHSA-2019:0365 https://access.redhat.com/errata/RHSA-2019:0380 https://access.redhat.com/errata/RHSA-2019:1106 https://access.redhat.com/errata/RHSA-2019:1107 https://access.redhat.com/errata/RHSA-2019:1108 https://access.redhat.com/errata/RHSA-2019:1140 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14642 https://access.redhat.com • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2018-14618 – curl: NTLM password overflow via integer overflow
https://notcve.org/view.php?id=CVE-2018-14618
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. • http://www.securitytracker.com/id/1041605 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:1880 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14618 https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf https://curl.haxx.se/docs/CVE-2018-14618.html https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2018-0014 https://security.gentoo.org/glsa/201903-03 https://usn.ubuntu.com/3765-1 https://usn.ubuntu.com/ • CWE-122: Heap-based Buffer Overflow CWE-131: Incorrect Calculation of Buffer Size CWE-190: Integer Overflow or Wraparound •
