AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Integer overflow in GNU Binutils 2.30's display_debug_ranges function allows denial of service via crafted ELF file.

Vulnerability

The vulnerability is an integer overflow in the display_debug_ranges function in dwarf.c of GNU Binutils version 2.30. It is triggered when processing a specially crafted ELF file, particularly when using the objdump utility to display debug information. The issue can cause an application crash due to the overflow. [3]

Exploitation

An attacker can exploit this by convincing a user to open or analyze a malicious ELF file with objdump or other affected Binutils tools. No authentication or special privileges are required; the attack is remote and relies on user interaction to trigger the vulnerable code path. [3]

Impact

Successful exploitation results in a denial of service through application crash. The official description also mentions a possibility of unspecified other impact, but no concrete outcome beyond disruption has been documented. [3]

Mitigation

The vulnerability is fixed in Binutils versions after 2.30. For Gentoo systems, upgrading to sys-devel/binutils-2.30-r2 or later is recommended [3]. No workaround is available; users should apply the latest updates from their distribution.
