CVE-2012-0029

Status: ModifiedHigh (7.4)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
