CVE-2018-19107 – exiv2: heap-based buffer over-read in Exiv2::IptcParser::decode in iptc.cpp
https://notcve.org/view.php?id=CVE-2018-19107
In Exiv2 0.26, Exiv2::IptcParser::decode in iptc.cpp (called from psdimage.cpp in the PSD image reader) may suffer from a denial of service (heap-based buffer over-read) caused by an integer overflow via a crafted PSD image file. En Exiv2 0.26, Exiv2::IptcParser::decode en iptc.cpp (llamado desde psdimage.cpp en el lector de imágenes PSD) puede sufrir una denegación de servicio (sobrelectura de búfer basada en memoria dinámica) causada por un desbordamiento de enteros a través de un archivo de imagen PSD manipulado. • https://access.redhat.com/errata/RHSA-2019:2101 https://github.com/Exiv2/exiv2/issues/427 https://github.com/Exiv2/exiv2/pull/518 https://lists.debian.org/debian-lts-announce/2019/02/msg00038.html https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html https://usn.ubuntu.com/4056-1 https://access.redhat.com/security/cve/CVE-2018-19107 https://bugzilla.redhat.com/show_bug.cgi?id=1649094 • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
CVE-2018-19058 – poppler: reachable abort in Object.h
https://notcve.org/view.php?id=CVE-2018-19058
An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file. Se ha descubierto un problema en Poppler 0.71.0. Hay un aborto alcanzable en Object.h, que conducirá a una denegación de servicio (DoS) debido a que EmbFile::save2 en FileSpec.cc carece de una comprobación de flujo antes de guardar un archivo embebido. • https://access.redhat.com/errata/RHSA-2019:2022 https://gitlab.freedesktop.org/poppler/poppler/issues/659 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.debian.org/debian-lts-announce/2022/09/msg00030.html https://usn.ubuntu.com/3837-1 https://access.redhat.com/security/cve/CVE-2018-19058 https://bugzilla.redhat.com/show_bug.cgi?id=1649435 • CWE-400: Uncontrolled Resource Consumption CWE-670: Always-Incorrect Control Flow Implementation •
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 •
