DATE CVE VULNERABILITY TITLE RISK
2019-01-03 CVE-2018-17161 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Freebsd 11.2/12.0
In FreeBSD before 11.2-STABLE(r348229), 11.2-RELEASE-p7, 12.0-STABLE(r342228), and 12.0-RELEASE-p1, insufficient validation of network-provided data in bootpd may make it possible for a malicious attacker to craft a bootp packet which could cause a stack buffer overflow.

2018-12-04 CVE-2018-17160 Out-of-bounds Write vulnerability in Freebsd
In FreeBSD before 11.2-STABLE(r341486) and 11.2-RELEASE-p6, insufficient bounds checking in one of the device models provided by bhyve can permit a guest operating system to overwrite memory in the bhyve host possibly permitting arbitrary code execution.

2018-12-04 CVE-2018-17157 Integer Overflow or Wraparound vulnerability in Freebsd
In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, an integer overflow error when handling opcodes can cause memory corruption by sending a specially crafted NFSv4 request.

2003-08-27 CVE-2003-0466 Off-by-one Error vulnerability in multiple products
Off-by-one error in the fb_realpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.
