UBUNTU-CVE-2018-18520 (CVE-2018-18520)

Vulnerability from osv_ubuntu – Published: 2018-10-19 00:00 – Updated: 2026-04-22 07:38 – Source website

Details

An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

UBUNTU-CVE-2019-7150 (CVE-2019-7150)

Vulnerability from osv_ubuntu – Published: 2019-01-28 00:00 – Updated: 2026-04-22 07:38 – Source website

Details

An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64_xlatetom in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service, as demonstrated by eu-stack.

UBUNTU-CVE-2019-7665 (CVE-2019-7665)

Vulnerability from osv_ubuntu – Published: 2019-02-09 00:00 – Updated: 2026-04-22 07:38 – Source website

Details

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.

UBUNTU-CVE-2020-21047 (CVE-2020-21047)

Vulnerability from osv_ubuntu – Published: 2023-08-22 19:16 – Updated: 2026-04-22 07:39 – Source website

Details

The libcpu component which is used by libasm of elfutils version 0.177 (git 47780c9e), suffers from denial-of-service vulnerability caused by application crashes due to out-of-bounds write (CWE-787), off-by-one error (CWE-193) and reachable assertion (CWE-617); to exploit the vulnerability, the attackers need to craft certain ELF files which bypass the missing bound checks.

Severity

5.5 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
