CVE-2013-6375
HighSummary
Xen w wersjach 4.2.x i 4.3.x, przy użyciu Intel VT-d do przekazywania PCI, nieprawidłowo opróżnia TLB po usunięciu wpisu z tabeli translacji, co pozwala lokalnym administratorom gości na spowodowanie odmowy usługi lub uzyskanie uprawnień poprzez nieokreślone wektory związane z 'odwróconym parametrem logicznym'.
Risk Assessment
Organizacja może być narażona na ataki, które prowadzą do odmowy usługi lub eskalacji uprawnień przez lokalnych administratorów gości, co może skutkować poważnymi konsekwencjami dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację do najnowszej wersji Xen, która zawiera poprawki dotyczące tej podatności oraz monitorowanie systemu w celu wykrycia potencjalnych prób wykorzystania tej luki.

Original NVD description (English source)
Xen 4.2.x and 4.3.x, when using Intel VT-d for PCI passthrough, does not properly flush the TLB after clearing a present translation table entry, which allows local guest administrators to cause a denial of service or gain privileges via unspecified vectors related to an "inverted boolean parameter."
