AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A heap-based buffer overflow in GNU Binutils 2.45's objcopy allows local attackers to cause a crash or potentially execute arbitrary code via a crafted object file.
Vulnerability
A heap-based buffer overflow vulnerability exists in GNU Binutils version 2.45, specifically in the copy_section function of binutils/objcopy.c. The issue arises from insufficient bounds checking when copying section data, leading to memory corruption on the heap.
Exploitation
Exploitation requires local access to the system. An attacker must provide a specially crafted object file that triggers the overflow when processed by objcopy. No special privileges are needed beyond local user access, making it a moderately low-barrier attack vector.
Impact
Successful exploitation could result in a denial-of-service condition (crash) or potentially arbitrary code execution in the context of the user running objcopy. The severity is rated Medium (CVSS 5.3) due to the local attack requirement.
Mitigation
The vendor has released a patch identified by commit 08c3cbe5926e4d355b5cb70bbec2b1eeb40c2944. Users are advised to apply this patch promptly. Siemens has acknowledged the vulnerability in their product lines, including SIMATIC S7-1500 TM MFP and S7-1500 CPU families [1][2], and recommends updating affected GNU/Linux subsystems.
