Description:
FreeBSD has acknowledged a security issue, which can be exploited by malicious people to conduct brute force attacks.
The security issue is caused due to the "arc4random()" function using insufficiently random entropy sources within the first 5 minutes after starting the boot process or until collecting enough random data. This weakens applications and processes relying on the security of "arc4random()" (e.g. when creating IVs for WEP, creating IP packet identifiers, kernel RPC transaction identifiers, and within GEOM ELI and GEOM shsec providers).
