CVSS: 9.8EPSS: 0%CPEs: 8EXPL: 0CVE-2018-12549 – JDK: missing null check when accelerating Unsafe calls
https://notcve.org/view.php?id=CVE-2018-12549
In Eclipse OpenJ9 version 0.11.0, the OpenJ9 JIT compiler may incorrectly omit a null check on the receiver object of an Unsafe call when accelerating it. En Eclipse OpenJ9 0.11.0, el compilador JIT de OpenJ9 podría omitir incorrectamente una comprobación nula en el objeto recibidor de una llamada no segura al acelerarla. • https://access.redhat.com/errata/RHSA-2019:0469 https://access.redhat.com/errata/RHSA-2019:0472 https://access.redhat.com/errata/RHSA-2019:0640 https://access.redhat.com/errata/RHSA-2019:1238 https://bugs.eclipse.org/bugs/show_bug.cgi?id=544019 https://access.redhat.com/security/cve/CVE-2018-12549 https://bugzilla.redhat.com/show_bug.cgi?id=1685717 • CWE-20: Improper Input Validation CWE-111: Direct Use of Unsafe JNI •
CVSS: 9.8EPSS: 1%CPEs: 8EXPL: 1CVE-2018-12547 – JDK: buffer overflow in jio_snprintf() and jio_vsnprintf()
https://notcve.org/view.php?id=CVE-2018-12547
In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer. This functions were not directly callable by non-native user code. En Eclipse OpenJ9, en versiones anteriores a la 0.12.0, los métodos nativos jio_snprintf() y jio_vsnprintf() ignoraban el parámetro length. Esto afecta a las API existentes que llamaban a las funciones para sobrepasar el búfer asignado. • https://access.redhat.com/errata/RHSA-2019:0469 https://access.redhat.com/errata/RHSA-2019:0472 https://access.redhat.com/errata/RHSA-2019:0473 https://access.redhat.com/errata/RHSA-2019:0474 https://access.redhat.com/errata/RHSA-2019:0640 https://access.redhat.com/errata/RHSA-2019:1238 https://bugs.eclipse.org/bugs/show_bug.cgi?id=543659 https://access.redhat.com/security/cve/CVE-2018-12547 https://bugzilla.redhat.com/show_bug.cgi?id=1685611 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2019-7664
In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash). En elfutils 0.175, se intenta realizar un memcpy de tamaño negativo en elf_cvt_note en libelf/note_xlate.h debido a una comprobación de desbordamiento incorrecta. Las entradas elf manipuladas provocan un fallo de segmentación, que conduce a una denegación de servicio (cierre inesperado del programa). • https://access.redhat.com/errata/RHSA-2019:2197 https://access.redhat.com/errata/RHSA-2019:3575 https://sourceware.org/bugzilla/show_bug.cgi?id=24084 https://access.redhat.com/security/cve/CVE-2019-7664 https://bugzilla.redhat.com/show_bug.cgi?id=1677536 • CWE-787: Out-of-bounds Write •

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes. En elfutils 0.175, existe una sobrelectura de búfer basada en memoria dinámica (heap) en la función elf32_xlatetom en elf32_xlatetom.c. Una entrada ELF manipulada puede provocar un fallo de segmentación que conduce a una denegación de servicio (cierre inesperado del programa) debido a que ebl_core_note no rechaza las notas de archivo core mal formadas. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://access.redhat.com/errata/RHSA-2019:3575 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=24089 https://sourceware.org/ml/elfutils-devel/2019-q1/msg00049.html https://usn.ubuntu.com/4012-1 https://access.redhat.com&#x • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 4%CPEs: 16EXPL: 1CVE-2018-16890 – curl: NTLM type-2 heap out-of-bounds buffer read
https://notcve.org/view.php?id=CVE-2018-16890
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds. Libcurl, desde la versión 7.36.0 hasta antes de la 7.64.0, es vulnerable a una lectura de memoria dinámica (heap) fuera de límites. La función que gestiona los mensajes entrantes NTLM de tipo 2 ("lib/vauth/ntlm.c:ntlm_decode_type2_target") no valida los datos entrantes correctamente y está sujeta a una vulnerabilidad de desbordamiento de enteros. • https://github.com/michelleamesquita/CVE-2018-16890 http://www.securityfocus.com/bid/106947 https://access.redhat.com/errata/RHSA-2019:3701 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16890 https://cert-portal.siemens.com/productcert/pdf/ssa-436177.pdf https://curl.haxx.se/docs/CVE-2018-16890.html https://lists.apache.org/thread.html/8338a0f605bdbb3a6098bb76f666a95fc2b2f53f37fa1ecc89f1146f%40%3Cdevnull.infra.apache.org%3E https://security.netapp.com/advisory/ntap-20190315-0001 https://sup • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
