Description Laura Pardo 2018-11-05 16:12:38 UTC
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 d_name(), d_encoding(), and d_local_name() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file.

Potentially a dupe of CVE-2018-18484, or at least the same root cause.
