CVSS: 7.5EPSS: 57%CPEs: 9EXPL: 1CVE-2019-9022 – php: memcpy with negative length via crafted DNS response
https://notcve.org/view.php?id=CVE-2019-9022
An issue was discovered in PHP 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.2. dns_get_record misparses a DNS response, which can allow a hostile DNS server to cause PHP to misuse memcpy, leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries. Se ha descubierto un problema en PHP, en versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.2. dns_get_record analiza erróneamente una respuesta DNS, lo que podría permitir que un servidor DNS hostil provoque que PHP emplee memcpy de forma incorrecta, lo que conduce a que las operaciones de lectura sobrepasen el búfer asignado para los datos DNS. Esto afecta a php_parserr en ext/standard/dns.c para las consultas DNS_CAA y DNS_ANY. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77369 https://lists.debian.org/debian-lts-announce/2019/03/msg00043.html https://security.netapp.com/advisory/ntap-20190321-0001 https://usn.ubuntu.com/3902-1 https://usn.ubuntu.com/3922-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 2%CPEs: 10EXPL: 1CVE-2019-9021 – php: Heap-based buffer over-read in PHAR reading functions
https://notcve.org/view.php?id=CVE-2019-9021
An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. A heap-based buffer over-read in PHAR reading functions in the PHAR extension may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse the file name, a different vulnerability than CVE-2018-20783. This is related to phar_detect_phar_fname_ext in ext/phar/phar.c. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.40, versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.1. Una sobrelectura de búfer basada en memoria dinámica (heap) en las funciones de lectura PHAR en la extensión PHAR podría permitir que un atacante lea memoria asignada o no asignada más allá de los datos reales al intentar analizar el nombre de archivo. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html http://www.securityfocus.com/bid/106747 http://www.securityfocus.com/bid/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php&# • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •

An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. Invalid input to the function xmlrpc_decode() can lead to an invalid memory access (heap out of bounds read or read after free). This is related to xml_elem_parse_buf in ext/xmlrpc/libxmlrpc/xml_element.c.

Las entradas inválidas en la función xmlrpc_decode() pueden conducir a un acceso inválido a la memoria (lectura de memoria dinámica o heap fuera de límites o lectura de memoria previamente liberada). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html http://www.securityfocus.com/bid/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77242 https://bugs. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read CWE-416: Use After Free •
CVSS: 9.8EPSS: 1%CPEs: 9EXPL: 0CVE-2018-20784 – kernel: infinite loop in update_blocked_averages() in kernel/sched/fair.c leading to denial of service
https://notcve.org/view.php?id=CVE-2018-20784
In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load. En el kernel de Linux, en versiones anteriores a la 4.20.2, kernel/sched/fair.c gestiona leaf cfs_rq de manera incorrecta, lo que permite que los atacantes provoquen una denegación de servicio (bucle infinito en update_blocked_averages) o, posiblemente, otro impacto sin especificar induciendo una carga alta. The CFS Linux kernel scheduler mishandles handling of leaf cfs_rq's in the kernel/sched/fair.c code, which allows a local unprivileged attacker to cause a denial of service (DoS) by entering an infinite loop in update_blocked_averages() function by inducing a high load on a system. Due to the nature of the flaw, a remote network attack (by initiating a magnitude of remote requests) cannot be fully ruled out. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c40f7d74c741a907cfaeb73a7697081881c497d0 https://access.redhat.com/errata/RHSA-2019:1959 https://access.redhat.com/errata/RHSA-2019:1971 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.20.2 https://github.com/torvalds/linux/commit/c40f7d74c741a907cfaeb73a7697081881c497d0 https://usn.ubuntu.com/4115-1 https://usn.ubuntu.com/4118-1 https://usn.ubuntu.com/4211-1 https://usn.ubuntu.com/4211-2 https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.8EPSS: 2%CPEs: 12EXPL: 0CVE-2019-8980 – kernel: memory leak in the kernel_read_file function in fs/exec.c allows to cause a denial of service
https://notcve.org/view.php?id=CVE-2019-8980
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures. Una fuga de memoria en la función kernel_read_file en fs/exec.c en el kernel de Linux, hasta la versión 4.20.11, permite que los atacantes provoquen una denegación de servicio (consumo de memoria) desencadenando errores en vfs_read. A kernel memory leak was found in the kernel_read_file() function in the fs/exec.c file in the Linux kernel. An attacker could use this flaw to cause a memory leak and thus a denial of service (DoS). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00052.html http://www.securityfocus.com/bid/107120 https://lists.debian.org/debian-lts-announce/2019/05/msg00002.html https://support.f5.com/csp/article/K56480726 https://usn.ubuntu.com/3930-1 https://usn.ubuntu.com/3930-2 https://usn.ubuntu.com/3931-1 https://usn.ubuntu.com/3931-2 https://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg1935698.html https://www.mail-archive.com/linux-kernel%40vg • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
