A security vulnerability has been detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_64_relocate_section of the file bfd/elf64-x86-64.c of the component ld. Such manipulation of the argument roff leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 2.48 addresses this issue. The name of the patch is 471130b39c03623ec6d78ece377ff4da3f6bfe7b. It is recommended to upgrade the affected component.
AnalysisAI
A heap out-of-bounds read/write leading to a buffer overflow exists in the GNU linker (ld), part of GNU Binutils 2.47, inside the elf_x86_64_relocate_section() function of bfd/elf64-x86-64.c, triggered when the linker processes a malformed x86-64 relocation entry whose roff argument is not validated. Exploitation is local — an attacker must supply a crafted ELF object file to a link operation — and yields only limited confidentiality, integrity and availability impact (CVSS 4.0 base 1.9), but publicly available exploit code exists and a heap OOB write/SEGV proof-of-concept has been published. …
