AI Insight

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

An integer underflow/overflow in BFD's DWARF handling in GNU Binutils 2.30 allows a denial of service via a crafted ELF file.

Vulnerability

In GNU Binutils 2.30, the dwarf2.c file in the Binary File Descriptor (BFD) library (libbfd) contains an integer underflow or overflow vulnerability when processing a corrupt DWARF FORM block in an ELF file. This can be triggered by providing a specially crafted ELF binary to utilities such as nm. [1][2][3]

Exploitation

An attacker can exploit this vulnerability by convincing a user to examine a malicious ELF file with any BFD-based tool (e.g., nm). No special privileges are required beyond local file access; the attack is remote in the sense that the malicious file can be downloaded from the internet or received by other means. [3]

Impact

Successful exploitation causes an application crash due to the integer underflow or overflow, leading to a denial of service. The vulnerability does not allow code execution or privilege escalation based on available information. [1][3]

Mitigation

Red Hat Enterprise Linux advisory RHSA-2018:3032 provides updated binutils packages that fix the vulnerability. [1] Gentoo users should upgrade to >=sys-devel/binutils-2.30-r2. [3] The advisory RHBA-2019:0327 for OpenShift Container Platform indirectly includes the fix in a broader image update. [2] No workaround is known; users must apply the updated package. [3]
