Linux systemd Affected by Memory Corruption Vulnerabilities, No Patches Yet (bleepingcomputer.com)

Major Linux distributions are vulnerable to three bugs in systemd, a Linux initialization system and service manager in widespread use, California-based security company Qualys said late yesterday. From a report: The bugs exist in 'journald' service, tasked with collecting and storing log data, and they can be exploited to obtain root privileges on the target machine or to leak information. No patches exist at the moment. Discovered by researchers at Qualys, the flaws are two memory corruption vulnerabilities (stack buffer overflow - CVE-2018-16864, and allocation of memory without limits - CVE-2018-16865) and one out-of-bounds error (CVE-2018-16866). They were able to obtain local root shell on both x86 and x64 machines by exploiting CVE-2018-16865 and CVE-2018-16866. The exploit worked faster on the x86 platform, achieving its purpose in ten minutes; on x64, though, the exploit took 70 minutes to complete. Qualys is planning on publishing the proof-of-concept exploit code in the near future, but they did provide details on how they were able to take advantage of the flaws.

    And this is the actual reason why people don't like systemd. It's quality is bad and when it crashes the kernel panics.

    We all panic.

    Good thing systemd alternatives haven't had any bugs ever!

    How dare you be reasonable and informative??? Didn't you get the memo regarding SystemD being shat directly from the bowels of Satan upon the innocent?

    You have unit filed which indicate after target they are a part

    Well, that made about as much sense as I'd expect from a defense of systemd.

    The developers weren't thinking about hostile input when they were writing code

    You'd think, by this point in time, Poettering would be very familiar with hostile input - heck, just look at most of the systemd discussions here on Slashdot!

    Can someone help me out and explain to me exactly what problem systemd solves?

    Red Hat did not have sufficient control over the Linux ecosystem. systemd is effectively addressing that problem.
