An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory access exists in _bfd_stab_section_find_nearest_line in syms.c. Attackers could leverage this vulnerability to cause a denial of service (application crash) via a crafted ELF file.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
