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.
AnalysisAI
GNU Binutils 2.47 contains a heap out-of-bounds write in the ELF .eh_frame handler _bfd_elf_write_section_eh_frame, triggered when a malformed object file causes the library to compute a negative size that is then passed to a memmove during section rewriting. The attack is local: an attacker must get a crafted ELF file processed by a BFD-based tool (such as ld, objcopy, or strip) on the target system, after which the process can corrupt heap memory and crash. …
