CVE-2020-25583

CVE-2020-25583 affects FreeBSD rtsold(8) handling of DNSSL and RDNSS options. The issue arises from insufficient bounds checking and incorrect validation of label lengths when decoding domain name labels (RFC 1035 encoding) in the DNSSL option, which could overflow the destination buffer. Affecte...

CVE-2020-25577

CVE-2020-25577 affects FreeBSD rtsold: insufficient bounds checking on RDNSS option extent (and related DNSSL handling) can allow malformed Router Advertisement data to flow to userspace, potentially enabling remote code execution in rtsold(8). Affects multiple FreeBSD branches (stable/11, stable...

CVE-2020-25577

In FreeBSD 12.2-STABLE before r368250, 11.4-STABLE before r368253, 12.2-RELEASE before p1, 12.1-RELEASE before p11 and 11.4-RELEASE before p5 rtsold8 does not verify that the RDNSS option does not extend past the end of the received packet before processing its contents. While the kernel currentl...

CVE-2020-25583: Buffer Copy without Checking Size of Input

In FreeBSD 12.2-STABLE before r368250, 11.4-STABLE before r368253, 12.2-RELEASE before p1, 12.1-RELEASE before p11 and 11.4-RELEASE before p5 when processing a DNSSL option, rtsold8 decodes domain name labels per an encoding specified in RFC 1035 in which the first octet of each label contains th...
