2DescriptionCVE.org
A security flaw has been discovered in GNU Binutils 2.47. This vulnerability affects the function elf_orphan_compatible of the file ld/ldelf.c of the component ELF Orphan Section Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet.
AnalysisAI
Null pointer dereference in GNU Binutils 2.47 crashes the ELF linker when processing orphan sections via a crafted object file. The flaw resides in the elf_orphan_compatible function in ld/ldelf.c, exploitable by any local user who can invoke the ld linker against a specially crafted ELF input. …
