CVE-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 •
CVE-2018-5407 – Intel (Skylake / Kaby Lake) - 'PortSmash' CPU SMT Side-Channel
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 •
CVE-2018-15688 – Out-of-Bounds write in systemd-networkd dhcpv6 option handling
https://notcve.org/view.php?id=CVE-2018-15688
A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239. Una vulnerabilidad de desbordamiento de búfer en el cliente dhcp6 de systemd permite que un servidor dhcp6 malicioso sobrescriba memoria dinámica (heap) en systemd-networkd. Las versiones afectadas de systemd son todas hasta la 239 incluida. It was discovered that systemd-network does not correctly keep track of a buffer size when constructing DHCPv6 packets. • http://www.securityfocus.com/bid/105745 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3665 https://access.redhat.com/errata/RHSA-2019:0049 https://github.com/systemd/systemd/pull/10518 https://lists.debian.org/debian-lts-announce/2018/11/msg00017.html https://security.gentoo.org/glsa/201810-10 https://usn.ubuntu.com/3806-1 https://usn.ubuntu.com/3807-1 https://access.redhat.com/security/cve/CVE-2018-15688 https:/ • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-122: Heap-based Buffer Overflow •
