FreeBSD -- IPv6 remote Denial-of-Service

Problem Description: Due do a missing check in the code of mpulldown9 data returned may not be contiguous as requested by the caller. Impact: Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS denial-of-service attack with certain Ethernet...

FreeBSD : FreeBSD -- IPv6 fragment reassembly panic in pf(4) (3d02520d-b309-11e9-a87f-a4badb2f4699)

A bug in the pf4 IPv6 fragment reassembly logic incorrectly uses the last extension header offset from the last received packet instead of from the first packet. Impact : Malicious IPv6 packets with different IPv6 extensions could cause a kernel panic or potentially a filtering rule bypass. C...

kernel: Buffer overflow in hidp_process_report

A buffer overflow due to a singed-unsigned comparsion was found in hidpprocessreport in the net/bluetooth/hidp/core.c in the Linux kernel. The buffer length is an unsigned int but gets cast to a signed int which in certain conditions can lead to a system panic and a denial-of-service...

FreeBSD -- ICMPv6 / MLDv2 out-of-bounds memory access

Problem Description: The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. Impact: A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page a...
