An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption problem caused by the cplus_demangle_type function making recursive calls to itself in certain scenarios involving many 'P' characters. Se ha descubierto una vulnerabilidad en cp-demangle.c en GNU libiberty, tal y como se distribuye en GNU Binutils 2.31. Hay un problema de consumo de pila causado por la función cplus_demangle_type que hace llamadas recursivas a sí misma en determinadas situaciones que involucran muchos caracteres "P". • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87335 https://usn.ubuntu.com/4326-1 https://usn.ubuntu.com/4336-1 • CWE-400: Uncontrolled Resource Consumption •

The convert_to_decimal function in vasnprintf.c in Gnulib before 2018-09-23 has a heap-based buffer overflow because memory is not allocated for a trailing '\0' character during %f processing. La función convert_to_decimal en vasnprintf.c en Gnulib en versiones anteriores al 2018-09-23 tiene un desbordamiento de búfer basado en memoria dinámica (heap) debido a que la memoria no se asigna para un carácter "\0" final durante el procesamiento de %f. • https://github.com/coreutils/gnulib/commit/278b4175c9d7dd47c1a3071554aac02add3b3c35 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A5UQRNQE6XHMD5UYYHAU3VQWAYHIPMQS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TMGHTVYH3KAFN34QXNSGEQDSTV7MCOQW https://lists.gnu.org/archive/html/bug-gnulib/2018-09/msg00107.html https://savannah.gnu.org/bugs/?func=detailitem&item_id=54686 • CWE-787: Out-of-bounds Write •

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. a heap-based buffer over-read in bfd_getl32 in libbfd.c allows an attacker to cause a denial of service through a crafted PE file. This vulnerability can be triggered by the executable objdump. Se ha detectado una vulnerabilidad en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31. Una sobrelectura de búfer basada en memoria dinámica (heap) en bfd_getl32 en libbfd.c permite que un atacante provoque una denegación de servicio (DoS) mediante un archivo PE manipulado. Esta vulnerabilidad puede ser desencadenada por el ejecutable objdump. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html https://sourceware.org/bugzilla/show_bug.cgi?id=23685 https://usn.ubuntu.com/4336-1 • CWE-125: Out-of-bounds Read •

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory access exists in _bfd_stab_section_find_nearest_line in syms.c. Attackers could leverage this vulnerability to cause a denial of service (application crash) via a crafted ELF file. Se ha detectado una vulnerabilidad en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.31.
