CVE-2013-2072
HighSummary
Przepełnienie bufora w powiązaniach Pythona dla wywołania xc_vcpu_setaffinity w Xen 4.0.x, 4.1.x i 4.2.x pozwala lokalnym administratorom z odpowiednimi uprawnieniami do konfiguracji powiązań VCPU na spowodowanie odmowy usługi (uszkodzenie pamięci i awaria narzędzia xend) oraz potencjalne uzyskanie uprawnień za pomocą spreparowanej mapy CPU.
Risk Assessment
Podatność ta może prowadzić do poważnych zakłóceń w działaniu systemu oraz umożliwić nieautoryzowanym użytkownikom uzyskanie wyższych uprawnień, co stanowi zagrożenie dla integralności i dostępności systemu.
Recommendation
Zaleca się aktualizację do najnowszej wersji Xen, która zawiera poprawki dla tej podatności oraz ograniczenie dostępu do funkcji konfiguracji VCPU tylko dla zaufanych administratorów.

Buffer overflow in the data receiving process in NEC WebSAM WinShare versions 7.5.0 and earlier, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary code with SYSTEM privileges via a crafted packet with a malformed data size value in the protocol header.
Original NVD description (English source)
Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap.
