CVE-2026-124747Busybox: heap buffer overflow in wget ftp resume when the resume offset exceeds the reported file size

Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Hardened Images Veröffentlicht: (gestern)

Beschreibung

A flaw was found in BusyBox. When resuming a download over File Transfer Protocol (FTP), the wget utility fails to verify that the resume offset does not exceed the file size reported by the server, resulting in an integer calculation error. A malicious FTP server or an on-path network attacker can exploit this issue by returning crafted file size metadata, triggering a heap-based buffer overflow with attacker-controlled data. Successful exploitation may allow an attacker to execute arbitrary code or crash the application, resulting in a denial of service (DoS).

Schwachstellentyp (CWE): CWE-787

Daten: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Wiedergegeben wie in der Quelle, auf Englisch.
