FreeBSD : FreeBSD -- IPv6 remote Denial-of-Service (4d3d4f64-f680-11e9-a87f-a4badb2f4699)

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 interfaces. At this...

FreeBSD -- Improper checking in SCTP-AUTH shared key update

Problem Description: The SCTP layer does improper checking when an application tries to update a shared key. Therefore an unprivileged local user can trigger a use-after- free situation, for example by specific sequences of updating shared keys and closing the SCTP association. Impact: Triggering...

FreeBSD 11.x < 11.2-RELEASE-p14 / 11.x < 11.3-RELEASE-p3 / 12.x < 12.0-RELEASE-p10 midistat Race Condition

The version of the FreeBSD kernel running on the remote host is 11.x prior to 11.2-RELEASE-p14, 11.x prior to 11.3-RELEASE-p3, or 12.x prior to 12.0-RELEASE-p10. It is, therefore, affected by an out-of-bounds memory access race condition in midistat. An authenticated attacker could exploit this,...

FreeBSD -- kernel memory disclosure from /dev/midistat

Problem Description: The kernel driver for /dev/midistat implements a handler for read2. This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer. Impact: The races allow a...

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...
