CVE-2020-7468 – FreeBSD FTPD Improper Handling of Exceptional Conditions Privilege Escalation Vulnerability

https://notcve.org/view.php?id=CVE-2020-7468

15 Dec 2020 — In FreeBSD 12.2-STABLE before r365772, 11.4-STABLE before r365773, 12.1-RELEASE before p10, 11.4-RELEASE before p4 and 11.3-RELEASE before p14 a ftpd(8) bug in the implementation of the file system sandbox, combined with capabilities available to an authenticated FTP user, can be used to escape the file system restriction configured in ftpchroot(5). Moreover, the bug allows a malicious client to gain root privileges.

CVE-2020-25577 – FreeBSD Security Advisory - FreeBSD-SA-20:32.rtsold

https://notcve.org/view.php?id=CVE-2020-25577

01 Dec 2020 — 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 rtsold(8) does not verify that the RDNSS option does not extend past the end of the received packet before processing its contents. While the kernel currently ignores such malformed packets, it passes them to userspace programs. Any programs expecting the kernel to do validation may be vulnerable to an overflow.

However, when processing subsequent options the packet buffer may be freed, rendering the cached pointer invalid. The network stack may later dereference the pointer, potentially triggering a use-after-free.
