CVE-2007-3268 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The TFTP implementation in IBM Tivoli Provisioning Manager for OS Deployment 5.1 before Fix Pack 3 allows remote attackers to cause a denial of service (rembo.exe crash and multiple service outage) via a read (RRQ) request with an invalid blksize (blocksize), which triggers a divide-by-zero error.. EPSS estimates a 2.23% chance of exploitation in the next 30 days.
