CVE-2018-1333 – DoS for HTTP/2 connections by crafted requests
https://notcve.org/view.php?id=CVE-2018-1333
By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33). Al manipular especialmente las peticiones HTTP/2, los trabajadores se asignarían 60 segundos más de los necesarios, lo que conduce a un agotamiento de los trabajadores y a una denegación de servicio (DoS). Esto se ha solucionado en Apache HTTP Server 2.4.34 (2.4.18 - 2.4.30, 2.4.33 afectadas). • http://www.securitytracker.com/id/1041402 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#CVE-2018-1333 https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E https://lists.apache.o • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-0495 – ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries
https://notcve.org/view.php?id=CVE-2018-0495
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. Libgcrypt en versiones anteriores a la 1.7.10 y versiones 1.8.x anteriores a la 1.8.3 permite un ataque de canal lateral por caché de memoria en las firmas ECDSA que se puede mitigar mediante el uso de la ocultación durante el proceso de firmado en la función _gcry_ecc_ecdsa_sign en cipher/ecc-ecdsa.c. Esto también se conoce como Return Of the Hidden Number Problem o ROHNP. Para descubrir una clave ECDSA, el atacante necesita acceso a la máquina local o a una máquina virtual diferente en el mismo host físico. • http://www.securitytracker.com/id/1041144 http://www.securitytracker.com/id/1041147 https://access.redhat.com/errata/RHSA-2018:3221 https://access.redhat.com/errata/RHSA-2018:3505 https://access.redhat.com/errata/RHSA-2019:1296 https://access.redhat.com/errata/RHSA-2019:1297 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2019:2237 https://dev.gnupg.org/T4011 https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVE-2018-10850 – 389-ds-base: race condition on reference counter leads to DoS using persistent search
https://notcve.org/view.php?id=CVE-2018-10850
389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service. 389-ds-base en versiones anteriores a la 1.4.0.10 y 1.3.8.3 es vulnerable a una condición de carrera por la forma en la que 389-ds-base gestiona las búsquedas persistentes.

CVE-2018-5848 – kernel: buffer overflow in drivers/net/wireless/ath/wil6210/wmi.c:wmi_set_ie() may lead to memory corruption
https://notcve.org/view.php?id=CVE-2018-5848
In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel. En la función wmi_set_ie(), el código de validación de longitud no gestiona correctamente los desbordamientos de enteros sin firmar. Como resultado, un gran valor del argumento "ie_len" puede provocar un desbordamiento de búfer en todas las distribuciones de Android de CAF (Android for MSM, Firefox OS for MSM, QRD Android) que utilizan el kernel de Linux.

CVE-2018-12020 – gnupg2: Improper sanitization of filenames allows for the display of fake status messages and the bypass of signature verification
https://notcve.org/view.php?id=CVE-2018-12020
mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. mainproc.c en GnuPG en versiones anteriores a la 2.2.8 gestiona de manera incorrecta el nombre de archivo original durante las acciones de descifrado y verificación, lo que permite que atacantes remotos suplanten la salida que GnuPG envía en el descriptor de archivo 2 a otros programas que emplean la opción "--status-fd 2". Por ejemplo, los datos OpenPGP podrían representar un nombre de archivo original que contiene caracteres de nueva línea junto con los códigos de estado GOODSIG o VALIDSIG. A data validation flaw was found in the way gnupg processes file names during decryption and signature validation. An attacker may be able to inject messages into gnupg verbose message logging which may have the potential to bypass the integrity of signature authentication mechanisms and could have other unintended consequences if applications take action(s) based on parsed verbose gnupg output. • http://openwall.com/lists/oss-security/2018/06/08/2 http://packetstormsecurity.com/files/152703/Johnny-You-Are-Fired.html http://seclists.org/fulldisclosure/2019/Apr/38 http://www.openwall.com/lists/oss-security/2019/04/30/4 http://www.securityfocus.com/bid/104450 http://www.securitytracker.com/id/1041051 https://access.redhat.com/errata/RHSA-2018:2180 https://access.redhat.com/errata/RHSA-2018:2181 https://dev.gnupg.org/T4012 https://github.com/RUB-NDS/Johnny • CWE-20: Improper Input Validation CWE-706: Use of Incorrectly-Resolved Name or Reference •
