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.
Se ha descubierto una vulnerabilidad en cp-demangle.c en GNU libiberty, tal y como se distribuye en GNU Binutils 2.31. La pila se agota en las funciones demangling en C++ proporcionadas por libiberty y hay un problema de consumo de pila provocado por tramas de pila recursivas: cplus_demangle_type, d_bare_function_type y d_function_type.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides the corresponding update for Ubuntu 16.04 ESM. It was discovered that GNU binutils contained a large number of security issues. If a user or automated system were tricked into processing a specially-crafted file, a remote attacker could cause GNU binutils to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
