Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations. Perl, en versiones anteriores a la 5.26.3 y versiones 5.28.0 anteriores a la 5.28.1, tiene un desbordamiento de búfer mediante una expresión regular manipulada que desencadena operaciones inválidas de escritura. • http://www.securityfocus.com/bid/106179 http://www.securitytracker.com/id/1042181 https://access.redhat.com/errata/RHSA-2019:0001 https://access.redhat.com/errata/RHSA-2019:0010 https://bugzilla.redhat.com/show_bug.cgi?id=1646734 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWQGEB543QN7SSBRKYJM6PSOC3RLYGSM https://metacpan.org/changes/release/SHAY/perl-5.26.3 https://metacpan.org/changes/release/SHAY/perl-5.28.1 https://rt.perl.org/Pub • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 9.8EPSS: 4%CPEs: 16EXPL: 1CVE-2018-8786 – freerdp: Integer truncation leading to heap-based buffer overflow in update_read_bitmap_update() function
https://notcve.org/view.php?id=CVE-2018-8786
FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function update_read_bitmap_update() and results in a memory corruption and probably even a remote code execution. FreeRDP en versiones anteriores a la 2.0.0-rc4 contiene un truncamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función zgfx_decompress() y que resulta en una corrupción de memoria y, probablemente, incluso en la ejecución remota de código. A flaw was found in freerdp in versions prior to version 2.0.0-rc4. An integer truncation that leads to a heap-based buffer overflow in the update_read_bitmap_update() function results in a memory corruption. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/106938 https://access.redhat.com/errata/RHSA-2019:0697 https://github.com/FreeRDP/FreeRDP/commit/445a5a42c500ceb80f8fa7f2c11f3682538033f3 https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YVJKO2DR5EY4C4QZOP7SNNBEW2JW6FHX https://research.checkpoint.com/reverse-rdp-attack-code-execution-on-rdp-clients https://usn.ubuntu.com/3845-1 https://usn.ubuntu.com/3845-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-680: Integer Overflow to Buffer Overflow CWE-681: Incorrect Conversion between Numeric Types CWE-787: Out-of-bounds Write •

CVSS: 7.5EPSS: 1%CPEs: 18EXPL: 0CVE-2018-12121 – nodejs: Denial of Service with large HTTP headers
https://notcve.org/view.php?id=CVE-2018-12121
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer. Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Denegación de servicio (DoS) con cabeceras HTTP grandes. Mediante la combinación de muchas peticiones con cabeceras de tamaño máximo (casi 80 KB por conexión) y al terminar a su debido tiempo las cabeceras, es posible provocar que el servidor HTTP aborte el fallo de asignación de memoria dinámica (heap). El potencial del ataque se ve mitigado por el uso de un balance de carga u otra capa del proxy. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://access.redhat.com/errata/RHSA-2019:2258 https://access.redhat.com/errata/RHSA-2019:3497 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12121 https://bugzilla.redhat.com/show_bug.cgi?id=1661002 • CWE-400: Uncontrolled Resource Consumption •

A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one. Se ha detectado un fallo de seguridad en el kernel de Linux de manera que el subsistema "cleancache" borre un inode después del truncado de archivos final (eliminación). El nuevo archivo creado con el mismo inode podría contener páginas restantes del "cleancache" y los datos antiguos del mismo, en vez de los del nuevo archivo. • http://www.securityfocus.com/bid/106009 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16862 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://lore.kernel.org/patchwork/patch/1011367 https://seclists.org/oss-sec/2018/q4/169 https://usn.ubuntu.com/3879-1 https://usn.ubuntu.com/3879-2 https://usn. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
