A vulnerability was detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_allocate_dynrelocs of the file bfd/elfxx-x86.c of the component Dynamic Relocation Allocation. The manipulation results in null pointer dereference. The attack requires a local approach. The exploit is now public and may be used. Upgrading to version 2.48 addresses this issue. The patch is identified as d1268210b6f6/471130b39c0/283d3198bed/0a84e560216/a692a633d40. Upgrading the affected component is recommended.
AnalysisAI
A null pointer dereference in GNU Binutils 2.47 lets a locally-supplied malformed ELF object crash the toolchain when the linker or related BFD-consuming utilities reach the elf_x86_allocate_dynrelocs() dynamic-relocation allocator in bfd/elfxx-x86.c. Only availability is impacted — the fault aborts the affected utility and no memory corruption, information disclosure, or code execution has been demonstrated, which is consistent with the CVSS 4.0 base score of 1.9 (AV:L/PR:L, VA:L only). …
