CVE-2012-0029
HighSummary
W podatności CVE-2012-0029 występuje przepełnienie bufora w stercie w funkcji process_tx_desc w emulacji e1000 w qemu-kvm 0.12, co pozwala użytkownikom systemu gościa na spowodowanie awarii QEMU oraz potencjalne wykonanie dowolnego kodu za pomocą spreparowanych pakietów w trybie legacy.
Risk Assessment
Podatność ta może prowadzić do awarii usług wirtualizacyjnych oraz umożliwić atakującym wykonanie nieautoryzowanego kodu, co stanowi poważne zagrożenie dla bezpieczeństwa systemów wirtualnych.
Recommendation
Zaleca się aktualizację do najnowszej wersji QEMU, aby zniwelować ryzyko związane z tą podatnością oraz monitorowanie systemów pod kątem nieautoryzowanych działań.

Original NVD description (English source)
Heap-based buffer overflow in the process_tx_desc function in the e1000 emulation (hw/e1000.c) in qemu-kvm 0.12, and possibly other versions, allows guest OS users to cause a denial of service (QEMU crash) and possibly execute arbitrary code via crafted legacy mode packets.
