FreeBSD : dnrd -- remote buffer and stack overflow vulnerabilities (e72fd82b-fa01-11d9-bc08-0001020eed82)
High Nessus Plugin ID 19358
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionNatanael Copa reports that dnrd is vulnerable to a remote buffer overflow and a remote stack overflow. These vulnerabilities can be triggered by sending invalid DNS packets to dnrd.
The buffer overflow could potentially be used to execute arbitrary code with the permissions of the dnrd daemon. Note that dnrd runs in an chroot environment and runs as non-root.
The stack overflow vulnerability can cause dnrd to crash.
SolutionUpdate the affected package.
