Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was detected in GNU Binutils 2.47. The affected element is the function _bfd_elf_strtab_delref of the file bfd/elf-strtab.c of the component ELF String Table. The manipulation results in memory corruption. The attack requires a local approach. 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.
AnalysisAI
Memory corruption in GNU Binutils 2.47 is triggerable locally by supplying a crafted ELF file to any Binutils tool that invokes _bfd_elf_strtab_delref in bfd/elf-strtab.c. A low-privileged local attacker can corrupt heap memory in the BFD library's ELF string table handler, potentially causing process crash, limited information disclosure, or minor data manipulation. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to a system with GNU Binutils 2.47 installed and the ability to invoke a Binutils tool (such as objcopy, ld, nm, or readelf) against an attacker-controlled ELF file. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 1.9 is notably low, consistent with a local, low-privilege attack yielding only partial (L/L/L) impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis - the upstream GNU Binutils project had not responded to the bug report (Bugzilla #34454) at time of disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
