The d_print_comp function in cp-demangle.c in libiberty allows remote attackers to cause a denial of service (segmentation fault and crash) via a crafted binary, which triggers infinite recursion and a buffer overflow, related to a node having "itself as ancestor more than once."
La función d_print_comp en cp-demangle.c en libiberty permite a atacantes remotos provocar una denegación de servicio (error de segmentación y caída) a través de un binario manipulado, que desencadena recursión infinita y un desbordamiento de búfer, relacionado con un nodo que se tiene "a sí mismo como ancestro más de una vez".
It was discovered that libiberty incorrectly handled certain string operations. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause libiberty to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. It was discovered that libiberty incorrectly handled parsing certain binaries. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause libiberty to crash, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Various other issues were also addressed.
