Описание
A flaw was found in vsftpd. This vulnerability allows a denial of service (DoS) via an integer overflow in the ls command parameter parsing, triggered by a remote, authenticated attacker sending a crafted STAT command with a specific byte sequence.
Отчет
Moderate impact affects Red Hat Enterprise Linux 8, 9, and 10 streams and Fedora 42 and 43, where vsftpd is affected. A remote, authenticated attacker can send a crafted STAT command containing a specific byte sequence to trigger an integer overflow in ls command parameter parsing and an infinite loop, resulting in denial of service. The CVSS v3.1 score is 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), consistent with the Moderate rating from both Red Hat and CVE.org. The affected entries are delegated and a fix is being pursued. The Fedora 42 and 43 entries carry unknown-component warnings in the current record. Red Hat Enterprise Linux 6 and 7 entries are marked out of support, while Red Hat In-Vehicle OS is not affected because the vulnerable code is not present.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
