In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party ** EN DISPUTA ** En ncurses 6.1, hay una desreferencia de puntero NULL en la función _nc_name_match que conducirá a un ataque de denegación de servicio (DoS). NOTA: el informe original indicaba la versión 6.1, pero el problema no se reprodujo para esa versión según mantenedor o un tercero fiable. • https://bugzilla.redhat.com/show_bug.cgi?id=1643753 • CWE-476: NULL Pointer Dereference •

CVE-2018-18701
https://notcve.org/view.php?id=CVE-2018-18701
An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions next_is_type_qual() and cplus_demangle_type() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm. Se ha descubierto una vulnerabilidad en cp-demangle.c en GNU libiberty, tal y como se distribuye en GNU Binutils 2.31. Hay una vulnerabilidad de consumo de pila que resulta de una recursión infinita en las funciones next_is_type_qual() y cplus_demangle_type() en cp-demangle.c. • https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87675 https://usn.ubuntu.com/4326-1 https://usn.ubuntu.com/4336-1 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

CVE-2018-18605
https://notcve.org/view.php?id=CVE-2018-18605
A heap-based buffer over-read issue was discovered in the function sec_merge_hash_lookup in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, because _bfd_add_merge_section mishandles section merges when size is not a multiple of entsize. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld. Se ha descubierto un problema de sobrelectura de búfer basada en memoria dinámica (heap) en la función sec_merge_hash_lookup en merge.c en la biblioteca Binary File Descriptor (BFD) (también conocida como libbfd), tal y como se distribuye en GNU Binutils 2.31. Esto se debe a que _bfd_add_merge_section gestiona de manera incorrecta las fusiones de sección cuando el tamaño no es un múltiplo de entsize. Un ELF especialmente manipulado permite que atacantes remotos provoquen una denegación de servicio (DoS), tal y como queda demostrado con Id. • 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/105754 https://security.netapp.com/advisory/ntap-20190307-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=23804 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=ab419ddbb2cdd17ca83618990f2cacf904ce1d61 https://usn.ubuntu.com/4336-1 • CWE-125: Out-of-bounds Read •
