An issue was discovered in GNU Binutils 2.32. It is a heap-based buffer overflow in process_mips_specific in readelf.c via a malformed MIPS option section.
A vulnerability was found in the readelf utility in GNU Binutils. This issue involves a heap-based buffer overflow in the process_mips_specific function, which can be triggered by a malformed MIPS option section in binary files.
Отчет
This vulnerability in GNU Binutils is considered moderate. While it involves a heap-based buffer overflow in the process_mips_specific function, successful exploitation requires the attacker to craft a specific malformed MIPS option section within a binary ELF file. This scenario limits the attack vector to files that the user explicitly processes with readelf, rather than making it exploitable through network services or untrusted inputs. Moreover, binutils does not handle privileged operations, meaning exploitation is unlikely to lead to system compromise or escalation of privileges. Additionally, the impact is localized to the application itself, without affecting the broader system or network security. Within regulated environments, a combination of the following controls acts as a significant barrier to the successful exploitation of a CWE-122: Heap-based Buffer Overflow vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Access to the platform is granted only after successful hard token, multi-factor authentication (MFA), which is coupled with least privilege principles to ensure that only authorized roles and users can execute or manipulate code. Red Hat enforces the principle of least functionality, ensuring that only essential features, services, and ports are enabled. This minimizes the number of components that could be affected by heap-based buffer overflow exploitations. The environment leverages malicious code protections such as IPS/IDS and antimalware solutions that detect and respond to indicators in real time, preventing or limiting the impact of exploitation attempts. Static code analysis and peer code review techniques ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks. Finally, memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) enhance resilience against memory buffer overflows and denial-of-service attacks.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
