A flaw was discovered in the HPACK decoder of HAProxy, before 1.8.14, that is used for HTTP/2. An out-of-bounds read access in hpack_valid_idx() resulted in a remote crash and denial of service. Se ha descubierto un fallo en el descodificador HPACK de HAProxy en versiones anteriores a la 1.8.14 que se utiliza para HTTP/2.

CVSS: 10.0EPSS: 1%CPEs: 11EXPL: 0CVE-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 •

A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections. Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en libtirpc en versiones anteriores a la 0.3.3-rc3. El valor de retorno de makefd_xprt() no se comprobó en todas las instancias, lo que podría conducir a un cierre inesperado cuando el servidor agotó el número máximo de descriptores de archivo disponibles. • http://git.linux-nfs.org/?p=steved/libtirpc.git%3Ba=commit%3Bh=1c77f7a869bdea2a34799d774460d1f9983d45f0 https://access.redhat.com/errata/RHBA-2017:1991 https://bugzilla.novell.com/show_bug.cgi?id=968175 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14622 https://lists.debian.org/debian-lts-announce/2018/08/msg00034.html https://usn.ubuntu.com/3759-1 https://usn.ubuntu.com/3759-2 • CWE-252: Unchecked Return Value •

CVSS: 7.8EPSS: 1%CPEs: 152EXPL: 0CVE-2018-5391 – The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets
https://notcve.org/view.php?id=CVE-2018-5391
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size. El kernel de Linux en versiones a partir de la 3.9 es vulnerable a un ataque de denegación de servicio (DoS) con tasas bajas de paquetes especialmente modificados que apuntan hacia el reensamblado de fragmentos de IP. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/105108 http://www.securitytracker.com/id/1041476 http://www.securitytracker.com/id/1041637 https://access.redhat.co • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
