GNU/Linux Security Leftovers

  • Major 9.8 vulnerability affects multiple Linux kernels— CVE-2019-8912 (af_alg_release())
    Our assessment is that the cause is this commit, the introduction of a "sockfs_setattr()" function. This function neglects to null-out values in a structure, making their values usable after exiting from the function (a so-called ‘use-after-free’ error).
  • Linux use-after-free vulnerability found in Linux 2.6 through 4.20.11
    Last week, a Huawei engineer reported a vulnerability present in the early Linux 2.6 kernels through version 4.20.11. The Kernel Address Sanitizer (KASAN) that detects dynamic memory errors within the Linux kernel code was used to uncover the use-after-free vulnerability which was present since early Linux versions. The use-after-free issue was found in the networking subsystem’s sockfs code and could lead to arbitrary code execution as a result.
  • Taking Care of Your Personal Online Security (For Paranoids)
    So, use Linux, and preferably coreboot or Libreboot (open source BIOS). You can buy hardware based on the recommendations of well-known and respected (still a bit paranoid) cypherpunk Richard Stallman.
  • Why do PAM projects fail? Tales from the trenches
    Privileged accounts hold the keys to highly sensitive company information and once these credentials are targeted, they can easily lead to a breach of a company’s most valuable assets; from databases to social media and unstructured data. Most enterprises have implemented some form of Privileged Access Management (PAM), but many find these initiatives fail to live up to expectations. Below are some common reasons why a PAM project might fail to meet the initial expectations; coupled with practical insights on how to prevent it from becoming a dud.
  • Sailfish OS: Security and Data Privacy
    Mobile World Congress is back again! Like every single year during the Jolla journey, we are excited to take part in this event. We have had great experiences in the past MWC’s, our main drivers for attending are the current and relevant topics discussed during the congress. One of this year’s core themes is Digital Trust; “Digital trust analyses the growing responsibilities required to create the right balance with consumers, governments and regulators.” It makes us happy that these topics are being discussed, especially since several scandals have recently affected trust in digital solutions. At Jolla we work constantly towards providing a secure and transparent solution. Our value towards our customer’s privacy is reflected in our values and actions. Back in May of 2018 our CEO Sami Pienimäki wrote a blog post on the GDPR laws passed within the European Union and stated the cornerstones on how Jolla views data privacy. This stand on privacy is not rocket science – the core idea is to respect our customers’ privacy and allow them to be in control of their data.
