CVE-2013-4527
HighSummary
Buffer overflow in hw/timer/hpet.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via vectors related to the number of timers.
Risk Assessment
This vulnerability could lead to remote code execution, posing a significant security risk to systems using QEMU.
Recommendation
It is recommended to update QEMU to version 1.7.2 or later to mitigate this vulnerability.
