Title
GNU Binutils Eh Frame Section elf-eh-frame.c _bfd_elf_write_section_eh_frame buffer overflow
Summary
A vulnerability was detected in GNU Binutils 2.47. Affected by this issue is the function _bfd_elf_write_section_eh_frame of the file bfd/elf-eh-frame.c of the component Eh Frame Section Handler. Performing a manipulation of the argument cie_length/fde_length/augmentation_data_size/write_offset results in buffer overflow. Attacking locally is a requirement. The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet.
