Description

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.

Technical Analysis

This vulnerability in GNU Binutils 2.47 involves a buffer overflow in the _bfd_elf_write_section_eh_frame function within the file bfd/elf-eh-frame.c. The issue is triggered by manipulating the arguments cie_length, fde_length, augmentation_data_size, or write_offset, causing a buffer overflow condition. Exploitation requires local access and user interaction. The vulnerability is publicly known, but no official vendor response or patch has been provided as of the publication date.

Potential Impact

Successful exploitation could lead to a buffer overflow condition on a local system, potentially allowing an attacker with local access and user interaction to cause memory corruption. The CVSS score of 2.4 indicates a low severity impact, suggesting limited potential for significant system compromise or remote exploitation.

Mitigation Recommendations

No official patch or vendor advisory is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict local access to trusted users only and avoid running untrusted code that could trigger this vulnerability.
