CVSS: 9.8EPSS: 1%CPEs: 7EXPL: 0CVE-2018-19115 – keepalived: Heap-based buffer overflow when parsing HTTP status codes allows for denial of service or possibly arbitrary code execution
https://notcve.org/view.php?id=CVE-2018-19115
keepalived before 2.0.7 has a heap-based buffer overflow when parsing HTTP status codes resulting in DoS or possibly unspecified other impact, because extract_status_code in lib/html.c has no validation of the status code and instead writes an unlimited amount of data to the heap. keepalived hasta la versión 2.0.8 tiene un desbordamiento de búfer basado en memoria dinámica (heap) cuando se analizan los códigos de estado HTTP, lo que resulta en una denegación de servicio (DoS) o, posiblemente, en otro impacto indeterminado, debido a que extract_status_code en lib/html.c no tiene ninguna validación del código de estado y, en su lugar, escribe una cantidad ilimitada de datos en la memoria dinámica. Heap-based buffer overflow vulnerability in extract_status_code() function in lib/html.c that parses HTTP status code returned from web server allows malicious web server or man-in-the-middle attacker pretending to be a web server to cause either a denial of service or potentially execute arbitrary code on keepalived load balancer. • https://access.redhat.com/errata/RHSA-2019:0022 https://access.redhat.com/errata/RHSA-2019:1792 https://access.redhat.com/errata/RHSA-2019:1945 https://bugzilla.suse.com/show_bug.cgi?id=1015141 https://github.com/acassen/keepalived/pull/961 https://github.com/acassen/keepalived/pull/961/commits/f28015671a4b04785859d1b4b1327b367b6a10e9 https://lists.debian.org/debian-lts-announce/2018/11/msg00034.html https://security.gentoo.org/glsa/201903-01 https://usn.ubuntu.com/3995-1 https:/& • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-5407
Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'. SMT (Simultaneous Multi-threading) en los procesadores puede habilitar que usuarios locales exploten software vulnerable a ataques de sincronización mediante un ataques de sincronización de canal lateral en la "contención de puertos". A microprocessor side-channel vulnerability was found on SMT (e.g, Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process can extract certain secret information. • https://www.exploit-db.com/exploits/45785 http://www.securityfocus.com/bid/105897 https://access.redhat.com/errata/RHSA-2019:0483 https://access.redhat.com/errata/RHSA-2019:0651 https://access.redhat.com/errata/RHSA-2019:0652 https://access.redhat.com/errata/RHSA-2019:2125 https://access.redhat.com/errata/RHSA-2019:3929 https://access.redhat.com/errata/RHSA-2019:3931 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
