Life post-acquisition: A people-centric plan to get you total data security a lot faster

Getting acquired can be an emotional rodeo. Some days are crazy excitement and others are heartache over the unknowns ahead. It’s natural – we’re human. I remember years ago sitting in a doctor’s office staring at a poster about the “10 most stressful life events” and “starting a new job” was 4...

CVE-2020-27174

In Amazon AWS Firecracker before 0.21.3, and 0.22.x before 0.22.1, the serial console buffer can grow its memory usage without limit when data is sent to the standard input. This can result in a memory leak on the microVM emulation thread, possibly occupying more memory than intended on the host...

CVE-2020-27173

In vm-superio before 0.1.1, the serial console FIFO can grow to unlimited memory usage when data is sent to the input source i.e., standard input. This behavior cannot be reproduced from the guest side. When no rate limiting is in place, the host can be subject to memory pressure, impacting all...

RUSTSEC-2020-0043 Insufficient size checks in outgoing buffer in ws allows remote attacker to run the process out of memory

Affected versions of this crate did not properly check and cap the growth of the outgoing buffer. This allows a remote attacker to take down the process by growing the buffer of their single connection until the process runs out of memory it can allocate and is killed. The flaw was corrected in t...
