A todo list will be left when the project end date is reached, for someone else to pick up. What Now: Not all protocols and layers of the network stack were verified, because of time constraints, and also because of unexpected events: the recent x86 CPU bugs, which I was the only one able to fix promptly. This flag is supposed to indicate that a given mbuf is the head of the chain it forms having the flag on secondary mbufs was suspicious. The IPsec Fragment Attack: I noticed some time ago that when reassembling fragments (in either IPv4 or IPv6), the kernel was not removing the M_PKTHDR flag on the secondary mbufs in mbuf chains. This could cause NPF to look for the L4 payload at the wrong offset within the packet, and it allowed an attacker to bypass any L4 filtering rule on IPv6. The NPF Integer Overflow: An integer overflow could be triggered in NPF, when parsing an IPv6 packet with large options. NetBSD replaced the macro with a sizeof(), which returns an unsigned result.

In the initial PF code a particular macro was used as an alias to a number. The PF Signedness Bug: A bug was found in NetBSD’s implementation of the PF firewall, that did not affect the other BSDs. Returning IPPROTO_NONE was entirely wrong: it caused the kernel to keep iterating on the IPv6 packet chain, while the packet storage was already freed. The IPPROTO Typo: While looking at the IPv6 Multicast code, I stumbled across a pretty simple yet pretty bad mistake: at one point the Pim6 entry point would return IPPROTO_NONE instead of IPPROTO_DONE. In addition this flaw allowed a limited buffer overflow - where the data being written was however not controllable by the attacker. As a result, a specially-crafted IPv6 packet could trigger an infinite loop in the kernel (making it unresponsive). The IPsec Infinite Loop: When receiving an IPv6-AH packet, the IPsec entry point was not correctly computing the length of the IPv6 suboptions, and this, before authentication. This allowed at least a pretty bad remote DoS/Crash The IPv6 Buffer Overflow: The overflow allowed an attacker to write one byte of packet-controlled data into ‘packet_storage+off’, where ‘off’ could be approximately controlled too. A lot of code is shared between the BSDs, so it is especially helpful when one finds a bug, to check the other BSDs and share the fix.In the course of investigating several bugs discovered in NetBSD, I happened to look at the network stacks of other operating systems, to see whether they had already fixed the issues, and if so how.
#Sourcetree authentication failed drivers
This was done in several layers of the NetBSD kernel, from device drivers to L4 handlers.

Dozens of bugs were fixed, among which a good number of actual, remotely-triggerable vulnerabilities.Ĭhanges were made to strengthen the networking subsystems and improve code quality: reinforce the mbuf API, add many KASSERTs to enforce assumptions, simplify packet handling, and verify compliance with RFCs. Over the last five months, hundreds of patches were committed to the source tree as a result of this work.

In addition to the 10 years of improvements from upstream, this version also has these NetBSD-specific enhancements:

This changes the upstream vendor from OpenSolaris to FreeBSD, and this version is based on FreeBSD svn r315983. Merge a new version of the CDDL dtrace and ZFS code.
#Sourcetree authentication failed windows
OpenZFS and DTrace updates in NetBSD, NetBSD network security stack audit, Performance of MySQL on ZFS, OpenSMTP results from p2k18, legacy Windows backup to FreeNAS, ZFS block size importance, and NetBSD as router on a stick.
