CVE-2018-7569 – binutils: integer underflow or overflow via an ELF file with a corrupt DWARF FORM block in libbfd library

https://notcve.org/view.php?id=CVE-2018-7569

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer underflow or overflow, and application crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm. dwarf2.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, permite que atacantes remotos provoquen una denegación de servicio (desbordamiento o subdesbordamiento de enteros y cierre inesperado de la aplicación) mediante un archivo ELF con un bloque DWARF FORM corrupto, tal y como demuestra nm. An integer wraparound has been discovered in the Binary File Descriptor (BFD) library distributed in GNU Binutils up to version 2.30. An attacker could cause a crash by providing an ELF file with corrupted DWARF debug information. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201811-17 https://sourceware.org/bugzilla/show_bug.cgi?id=22895 https://access.redhat.com/security/cve/CVE-2018-7569 https://bugzilla.redhat.com/show_bug.cgi?id=1551778 • CWE-190: Integer Overflow or Wraparound CWE-191: Integer Underflow (Wrap or Wraparound) •

CVE-2018-7570

https://notcve.org/view.php?id=CVE-2018-7570

The assign_file_positions_for_non_load_sections function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an ELF file with a RELRO segment that lacks a matching LOAD segment, as demonstrated by objcopy. La función assign_file_positions_for_non_load_sections en elf.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) mediante un archivo ELF con un segmento RELRO que carece de un segmento LOAD que coincida, tal y como demuestra objcopy. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html https://security.gentoo.org/glsa/201811-17 https://sourceware.org/bugzilla/show_bug.cgi?id=22881 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=01f7e10cf2dcf403462b2feed06c43135651556d • CWE-476: NULL Pointer Dereference •

CVE-2018-7568 – binutils: integer overflow via an ELF file with corrupt dwarf1 debug information in libbfd library

https://notcve.org/view.php?id=CVE-2018-7568

The parse_die function in dwarf1.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer overflow and application crash) via an ELF file with corrupt dwarf1 debug information, as demonstrated by nm. La función parse_die en dwarf1.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de enteros y cierre inesperado de la aplicación) mediante un archivo ELF con información de depuración corrupta, tal y como demuestra nm. An integer wraparound has been discovered in the Binary File Descriptor (BFD) library distributed in GNU Binutils up to version 2.30. An attacker could cause a crash by providing an ELF file with corrupted DWARF debug information. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201811-17 https://sourceware.org/bugzilla/show_bug.cgi?id=22894 https://access.redhat.com/security/cve/CVE-2018-7568 https://bugzilla.redhat.com/show_bug.cgi?id=1551771 • CWE-190: Integer Overflow or Wraparound •

CVE-2018-7208 – binutils: Improper bounds check in coffgen.c:coff_pointerize_aux() allows for denial of service when parsing a crafted COFF file

https://notcve.org/view.php?id=CVE-2018-7208

In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object. En la función coff_pointerize_aux en coffgen.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, no se valida un índice. Esto permite que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) o que pueda provocar otro tipo de impacto sin especificar mediante un archivo manipulado, tal y como demuestra un objcopy de un objeto COFF. • 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/103077 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3032 https://security.gentoo.org/glsa/201811-17 https://sourceware.org/bugzilla/show_bug.cgi?id=22741 https://access.redhat.com/security/cve/CVE-2018-7208 https://bugzilla.redhat.com/show_bug.cgi?id=15 • CWE-20: Improper Input Validation •
