CVE-2018-20650 – poppler: reachable Object::dictLookup assertion in FileSpec class in FileSpec.cc
https://notcve.org/view.php?id=CVE-2018-20650
A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in FileSpec.cc) in pdfdetach. Una aserción alcanzable en Object::dictLookup en Poppler 0.72.0 permite a los atacantes provocar una denegación de servicio (DoS) debido a la falta de comprobación del tipo de datos del directorio, tal y como queda demostrado con el uso de la clase FileSpec (en FileSpec.cc) en pdfdetach. • http://www.securityfocus.com/bid/106459 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://gitlab.freedesktop.org/poppler/poppler/commit/de0c0b8324e776f0b851485e0fc9622fc35695b7 https://gitlab.freedesktop.org/poppler/poppler/issues/704 https://lists.debian.org/debian-lts-announce/2019/09/msg00033.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.debian.org/debian-lts-announce/2022/09/msg00030.html https:/ • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVE-2018-1000876 – binutils: integer overflow leads to heap-based buffer overflow in objdump
https://notcve.org/view.php?id=CVE-2018-1000876
binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to be exploitable via Local. This vulnerability appears to have been fixed in after commit 3a551c7a1b80fca579461774860574eabfd7f18f. binutils, en versiones 2.32 y anteriores, contiene una vulnerabilidad de desbordamiento de enteros en objdump, bfd_get_dynamic_reloc_upper_bound y bfd_canonicalize_dynamic_reloc que puede resultar en un desbordamiento de enteros que desencadena un desbordamiento de memoria dinámica (heap). Si se explota con éxito, podría conducir a la ejecución de código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html http://www.securityfocus.com/bid/106304 https://access.redhat.com/errata/RHSA-2019:2075 https://sourceware.org/bugzilla/show_bug.cgi?id=23994 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=3a551c7a1b80fca579461774860574eabfd7f18f https://usn.ubuntu.com/4336-1 https://access.redhat.com/security/cve/CVE-2018-1000876 https://bugzilla. • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
