OpenWRT Package Checksums Not Checked Opening MITM Opportunities And Further Downstream Havok

Alternative router firmware distribution OpenWRT is seeing a vulnerability allowing its package manager to be MITM'd publicized (archived). OpenWRT's fork of opkg, used as a package manager and running as root, fails to check checksums when parsing package lists. Successful use of the MITM to place a payload opens the rest of the doors to ownership. Routing remains a live battleground.

OpenBSD Mail Server OpenSMTPD Allows Remote Exectution Of Arbitrary Shell Commands As Root

A remotely-exploitable vulnerability for OpenSMTPD, OpenBSD's mail server, present since May 2018, has been made public (archived). It enables an attacker to execute arbitrary shell commands with root privileges.

Notably, the proof-of-concept exploit makes use of routines which first made an appearance in the Morris worm of 1988.

Entire Argentine Judiciary Paralyzed As Computers Stop Working For Them

Argentina's courts are paralyzed after the Lex100 system they use for everything stopped working six days ago (archived). This is not the first time the system has gone down (archived), but it is the longest time Argentina's courts have been without this one system they built everything they do around. This makes the pretense of Argentina having a legal profession still more laughable than it already was. Continue reading

Oracle Appears To Join Microsoft In Re-Keying NSA Backdoors With 334 "Security" Patches In Dump

Oracle has released security 334 patches across 93 products to deal with a variety of issues, and many of the things being patched against are exploitable remotely (archived). Earlier this week Microsoft hyped their release of USG.NSA endorsed changes to crypt32.dll with great urgency.

USG.NSA And Microsoft Push "Emergency" Windows Crypto Update While Depreciating Windows 7

Yesterday's "Patch Tuesday" for Microsoft Windows included a "fix" promoted loudly through USG alligned media outlets that allegedly repairs X.509 "PKI" certificate validation in Microsoft's crypt32.dll (archived). The usual suspects are loudly herding Windows users to update in a way that strongly suggests geopolitical considerations may have pushed the USG.NSA to burn a number of their cultivated backdoors as they tend to do from time to time.

Past behavior of the actors involved suggests that as before, the patch is not going to be an actual fix so much as a subtle rekeying of the orfice. Serendipitously this patch was released immediately after Microsoft stopped issuing patches for Windows 7 creating an intense opportunity for Microsoft to collect "upgrade license" revenue with the endorsement of the USG "National Security" apparatus using the pitch that the USG already adopted the upgrade for its machines. The line between USG agency and USG "enterprise" continues become increasingly squishy.

The is the first time the USG.NSA has allowed itself to be explicitly named in Microsoft marketing materials as the contributor to a "fix" suggesting an ongoing marketing partnership between the two may be budding.

One Week After Grave Vulnerability Revealed, WireGuard Moving Into Linux Kernel For 5.6

Linux kernel network stack maintainer and GCC steering committee member David S. Miller has committed WireGuard VPN into the net-next tree all but assuring that the VPN software will become part of the Linux 5.6 kernel release (archived). This comes less than one week after revelations that most VPN implementations, including WireGuard, are vulnerable to session hijacking on most *nix network stacks. At this time WireGuard is being implemented into kernel as a standalone module with CONFIG_WIREGUARD and CONFIG_WIREGUARD_DEBUG menu options.

Linus Torvalds stepped down from his former position actively shaping Linux kernel development back in September 2018 after he took his intersectional daughter's suggestions seriously.

VPN Breaking Zero Day Effective Against Many *nix Systems Burned

RecentlyBurnedWorkandLivingVanA zero day that allows nearby network actors to detect and inject payloads into VPN tunnels has been revealed (archived). All VPN implementations appear to be affected including allegedly "hardened" ones like WireGuard and IKEv2/IPSec while the vulnerability hits numerous *nix TCP/IP stacks including those by Apple, Google, OpenBSD, and Linux. Linux appear to be most gravely affected when running versions of systemd published after November 28th, 2018 when the default "reverse ip path filtering" default was changed to more easily facilitate hijacking VPN sessions in this manner.

The original disclosures to the Openwall oss-security mailing lists are presented in full below: Continue reading

Python Runtime Differences Across Platforms Do Different Math

A group of chemists at the University of Hawaii published a paper in Organic Letters documenting numerous ways that the math performed by Python differs across the operating systems Python code can be run on (archived). The scripts revealing Pythonistic mathematics to be operating system dependent were intended to process nuclear magnetic resonance spectroscopy data. The scripts were originally described in Nature Protocols in 2014 went so far as to offer differing results across Mac OS X releases. This is far from the first indictment of misapplying computing tools in the modeling of reality.
