An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions next_is_type_qual() and cplus_demangle_type() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
