CVE-2010-4251
HighSummary
Implementacja gniazd w jądrze Linux przed wersją 2.6.34 nie zarządza prawidłowo kolejką odebranych pakietów. Umożliwia to zdalnym atakującym spowodowanie odmowy usługi (zużycie pamięci) poprzez wysyłanie dużej ilości ruchu sieciowego.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do przeciążenia systemu, co prowadzi do jego niedostępności. Może to wpłynąć na ciągłość działania usług w organizacji.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.34 lub nowszej, aby usunąć tę podatność. Dodatkowo warto monitorować ruch sieciowy w celu wykrywania 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.
- CVE-2026-124490Critical
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 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.
