CVE-2025-11083: Heap-based Buffer Overflow in GNU Binutils
A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended to deploy a patch. The code maintainer replied with "[f]ixed for 2.46".
AI Analysis
Technical Summary
The vulnerability in GNU Binutils 2.45 involves a heap-based buffer overflow in the elf_swap_shdr function of the bfd/elfcode.h component used by the linker. This flaw can be exploited locally to cause memory corruption. The maintainer has fixed the issue in version 2.46, and the patch is identified by commit 9ca499644a21ceb3f946d1c179c38a83be084490. The CVSS 4.0 vector indicates low attack complexity and requires local privileges without user interaction.
Potential Impact
Successful exploitation of this vulnerability could lead to heap memory corruption, potentially causing application crashes or arbitrary code execution under local attacker control. The attack requires local access and privileges, limiting remote exploitation. The medium CVSS score reflects moderate impact due to the local attack vector and required privileges.
Mitigation Recommendations
A fix is available in GNU Binutils version 2.46. It is recommended to upgrade from version 2.45 to 2.46 or later to remediate this vulnerability. No additional vendor advisories indicate alternative mitigations or that no action is required.
