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. There is a NULL pointer dereference in _bfd_add_merge_section when attempting to merge sections with large alignments. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld. Se ha descubierto un problema en la función merge_strings en merge.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31.

An issue was discovered in elf_link_input_bfd in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in elf_link_input_bfd when used for finding STT_TLS symbols without any TLS section. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld. Se ha descubierto un problema en elf_link_input_bfd en elflink.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31.

The get_count function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote attackers to cause a denial of service (malloc called with the result of an integer-overflowing calculation) or possibly have unspecified other impact via a crafted string, as demonstrated by c++filt. La función get_count en cplus-dem.c en GNU libiberty, tal y como se distribuye en GNU Binutils 2.31, permite que atacantes remotos provoquen una denegación de servicio (malloc llamado con el resultado de un cálculo que desborda un entero) o, posiblemente, otro tipo de impacto sin especificar mediante una cadena manipulada, tal y como queda demostrado por c++filt. • 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/105689 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87602 https://sourceware.org/bugzilla/show_bug.cgi?id=23767 https://usn.ubuntu.com/4326-1 https://usn.ubuntu.com/4336-1 • CWE-190: Integer Overflow or Wraparound •

An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there is a stack consumption problem caused by recursive stack frames: cplus_demangle_type, d_bare_function_type, d_function_type.
