An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h because the number of program headers is not restricted. Se ha descubierto un problema en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31. Hay un desbordamiento de búfer basado en memoria dinámica (heap) en bfd_elf32_swap_phdr_in en elfcode.h debido a que el número de cabeceras del programa no está restringido. • 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/106144 https://security.gentoo.org/glsa/201908-01 https://security.netapp.com/advisory/ntap-20190221-0004 https://sourceware.org/bugzilla/show_bug.cgi?id=23942 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=5f60af5d24d181371d67534fa273dd221df20c07 https://usn.ubuntu.com/4336-1 • CWE-787: Out-of-bounds Write •

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') •

An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31.

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 •

An issue was discovered in the merge_strings function in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31.
