CVE-2010-4805
HighSummary
Implementacja gniazd w jądrze Linux przed wersją 2.6.35 nie zarządza prawidłowo kolejką odebranych pakietów, co pozwala zdalnym atakującym na spowodowanie odmowy usługi poprzez wysyłanie dużej ilości ruchu sieciowego. Problem dotyczy funkcji sk_add_backlog oraz pola sk_rmem_alloc w gniazdach.
Risk Assessment
Organizacja może doświadczyć odmowy usługi, co prowadzi do zakłóceń w dostępności usług sieciowych. Atakujący mogą wykorzystać tę podatność do przeciążenia systemu.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.35 lub nowszej, aby usunąć tę podatność. Należy również monitorować ruch sieciowy w celu wykrycia potencjalnych ataków.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.

OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
Original NVD description (English source)
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4251.
