Exploit

GNU Binutils Eh Frame Section elf-eh-frame.c _bfd_elf_write_section_eh_frame buffer overflow

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.

CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer

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.

CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.
