CWE

KEV

CWE ID	Description
CWE-119	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.

Attack-Flow Graph

Executive Summary

This vulnerability is in GNU Binutils 2.47, specifically in the _bfd_elf_strtab_delref function of the bfd/elf-strtab.c file. It causes memory corruption and can be exploited locally. The exploit is publicly available, and the project was notified but has not responded yet.

Detection Guidance

This vulnerability involves memory corruption in GNU Binutils 2.47, specifically in the _bfd_elf_strtab_delref function. Detection may require manual code review or dynamic analysis tools like AddressSanitizer (ASan) to identify memory corruption issues during execution.

Impact Analysis

The vulnerability allows local attackers to corrupt memory, potentially leading to crashes or arbitrary code execution. Since the exploit is public, attackers could use it to gain unauthorized access or escalate privileges on affected systems.

Compliance Impact

The vulnerability in GNU Binutils 2.47 involves memory corruption in the ELF String Table function, which could lead to unauthorized access or data leaks. This may impact compliance with GDPR (data protection) and HIPAA (health data security) by potentially exposing sensitive information. However, specific compliance impacts depend on system configuration and data handling practices.

Mitigation Strategies

Update GNU Binutils to a version that addresses this vulnerability. If an update is not available, consider disabling or restricting access to affected components until a patch is released.
