CVE-2009-2526
HighSummary
Podatność w systemach Microsoft Windows Vista i Server 2008 polega na niewłaściwej walidacji pól w pakietach SMBv2, co może prowadzić do zdalnego wywołania odmowy usługi poprzez specjalnie przygotowany pakiet. Problem ten jest znany jako 'Podatność na nieskończoną pętlę SMBv2'.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do spowodowania zawieszenia systemu, co prowadzi do przerwy w dostępności usług. Może to wpłynąć na ciągłość działania organizacji oraz jej reputację.
Recommendation
Zaleca się aktualizację systemów do najnowszych wersji, które zawierają poprawki zabezpieczeń eliminujące tę podatność. Należy również monitorować ruch sieciowy w celu wykrywania potencjalnych prób ataków.

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.

Original NVD description (English source)
Microsoft Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2 do not properly validate fields in SMBv2 packets, which allows remote attackers to cause a denial of service (infinite loop and system hang) via a crafted packet to the Server service, aka "SMBv2 Infinite Loop Vulnerability."
