A flaw was found in binutils, where GNU GCC is vulnerable to a denial of service caused by a stack consumption in the demangle_const() function in ibiberty/rust-demangle.c. The vulnerability exists due to the application not properly controlling the consumption of internal resources. By persuading a victim to open a specially-crafted file, an attacker could cause a denial of service.
