CVE-2010-0022
HighSummary
Implementacja SMB w usłudze serwera w systemach Microsoft Windows 2000 SP4, Windows XP SP2 i SP3, Windows Server 2003 SP2, Windows Vista oraz Windows 7 nieprawidłowo waliduje pola share i servername w pakietach SMB. To umożliwia zdalnym atakującym spowodowanie odmowy usługi (zawieszenie systemu) poprzez odpowiednio skonstruowany pakiet.
Risk Assessment
Podatność ta może prowadzić do poważnych zakłóceń w działaniu systemów, co może wpłynąć na dostępność usług w organizacji. Atakujący mogą wykorzystać tę lukę do zdalnego zawieszania systemów.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które zawierają poprawki zabezpieczeń. Należy również rozważyć ograniczenie dostępu do usług SMB z niezaufanych źródeł.

imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
- CVE-2026-123551Critical
OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
- CVE-2026-123550Critical
OpenAM before 16.1.4 contains an authentication bypass vulnerability in its SAML v2.0 service provider that accepts unsigned assertions on the ECP (PAOS) and HTTP-Artifact bindings when WantAssertionsSigned is false. Unauthenticated remote attackers can submit forged assertions to obtain sessions as any mapped user, including administrators, and hijack single sign-on to dependent applications.
- CVE-2026-123549Critical
OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.

- CVE-2026-124057Critical
A security flaw has been discovered in TOTOLINK CA300-PoE 6.2c.884. This impacts the function setWiFiMultipleConfig of the file /cgi-bin/cstecgi.cgi. Manipulation of the argument Key1Str1 results in a buffer overflow. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks.
- CVE-2026-123966Critical
A vulnerability was found in Tenda AC19 version 16.03.10.07 in the saveParentControlInfo function of the /goform/saveParentControlInfo file. Manipulating the deviceId argument causes a heap-based buffer overflow. The attack can be carried out remotely, and the exploit has been publicly disclosed.
- CVE-2026-120984Critical
A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during setup.

Original NVD description (English source)
The SMB implementation in the Server service in Microsoft Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate the share and servername fields in SMB packets, which allows remote attackers to cause a denial of service (system hang) via a crafted packet, aka "SMB Null Pointer Vulnerability."
