CVE-2013-4541

20
FAUCET Score

CVE-2013-4541 describes a vulnerability in QEMU versions prior to 1.7.2, specifically within the usb_device_post_load function, which could allow remote attackers to execute arbitrary code. This high-severity vulnerability (CVSS 7.5) is due to improper handling of negative setup_len or setup_index values in a crafted savevm image, potentially leading to compromise of confidentiality, integrity, and availability. While no public exploit intelligence, Metasploit modules, or social media discussion are currently identified, the potential for remote code execution warrants attention.
