Exploitability
| 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. |
| CWE-122 | A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). |
Attack-Flow Graph
AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a heap-based buffer overflow in the function elf_x86_64_relocate_section of the file elf64-x86-64.c in GNU Binutils 2.45. It occurs locally and allows an attacker with local access to potentially cause a buffer overflow by manipulating the linker component.
How can this vulnerability impact me? :
The vulnerability can lead to a heap-based buffer overflow when exploited locally, which may cause application crashes or potentially allow an attacker to execute arbitrary code or disrupt system availability. However, the impact is limited as the attack requires local access and the CVSS scores indicate a low to moderate severity with no confidentiality or integrity impact but some availability impact.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, it is recommended to deploy the patch identified by commit 6b21c8b2ecfef5c95142cbc2c32f185cb1c26ab0 for GNU Binutils 2.45. Additionally, since the attack requires local access, restricting local user privileges and access can help reduce risk.
