GNU Binutils, Memory Corruption, CVE-2025-1179 (Critical)

By /

How the CVE Works:

CVE-2025-1179 is a critical memory corruption vulnerability found in GNU Binutils version 2.43. The issue resides in the `bfd_putl64` function within the `bfd/libbfd.c` file, a core component of the `ld` linker. This function mishandles memory operations, leading to corruption when processing maliciously crafted input files. Attackers can exploit this vulnerability remotely, though the complexity of the attack is high due to the need for precise memory manipulation. Exploitation could allow arbitrary code execution or crashes, potentially compromising systems. The vulnerability has been patched in GNU Binutils 2.44, and users are strongly advised to upgrade to this version to mitigate the risk.
