In particular, it does not verify that the + option does not extend past the end of the received packet before + processing its contents. The kernel currently ignores such + malformed packets but still passes them to userspace programs.</p> + <p>Second, when processing a DNSSL option, rtsold(8) decodes domain + name labels per an encoding specified in RFC 1035 in which the first + octet of each label contains the label's length. rtsold(8) did not + validate label lengths correctly and could overflow the destination + buffer.</p> + <h1>Impact:</h1> + <p>It is believed that these bugs could be exploited to gain remote + code execution within the rtsold(8) daemon, which runs as root. + Note that rtsold(8) only processes messages received from hosts + attached to the same physical link as the interface(s) on which + rtsold(8) is listening.</p> + <p>In FreeBSD 12.2 rtsold(8) runs in a Capsicum sandbox, limiting the + scope of a compromised rtsold(8) process.</p> + </body> + </description> + <references> + <cvename>CVE-2020-25577</cvename> + <freebsdsa>SA-20:32.rtsold</freebsdsa> + </references> + <dates> + <discovery>2020-12-01</discovery> + <entry>2020-12-02</entry> + </dates> + </vuln> + <vuln vid="8eed0c5c-3482-11eb-b87a-901b0ef719ab"> <topic>FreeBSD -- ICMPv6 use-after-free in error message handling</topic> <affects>
