CVE-2012-0028
HighSummary
Wersje jądra Linux przed 2.6.28 mają wadliwą implementację futex, która nieprawidłowo obsługuje procesy wykonujące wywołania systemowe exec. To może umożliwić lokalnym użytkownikom spowodowanie odmowy usługi lub potencjalne uzyskanie uprawnień przez zapis do lokalizacji pamięci w procesie potomnym.
Risk Assessment
Organizacja może być narażona na ataki lokalnych użytkowników, którzy mogą wykorzystać tę podatność do zakłócenia działania systemu lub uzyskania nieautoryzowanych uprawnień.
Recommendation
Zaleca się aktualizację jądra Linux do wersji 2.6.28 lub nowszej, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia potencjalnych prób jej wykorzystania.

The Melapress Role Editor plugin for WordPress (through version 1.3.0) contains an incorrect privilege assignment vulnerability that allows privilege escalation. A low-privileged user can gain a higher level of access within the system.
Original NVD description (English source)
The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.
