Description Laura Pardo 2018-12-21 13:43:44 UTC
A flaw was found in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. A memory leak via a crafted ELF file in the _bfd_generic_read_minisymbols function in syms.c. This could lead to a denial of service attack (memory consumption).
