CVE-2021-0393

In Scanner::LiteralBuffer::NewCapacity of scanner.cc, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution if an attacker can supply a malicious PAC file, with no additional execution privileges needed. User interaction is not needed for...

Grid. Locked.

In the UK we are used to having a reliable and stable electricity grid. So stable that you can keep time with it. Before quartz clocks became common, mains powered clocks used the electricity grid frequency of 50Hz as their time reference, you can still find the odd central heating timer or old...

RUSTSEC-2021-0050 swap_index can write out of bounds and return uninitialized memory

swapindex takes an iterator and swaps the items with their corresponding indexes. It reserves capacity and sets the length of the vector based on the .len method of the iterator. If the len returned by the iterator is larger than the actual number of elements yielded, then swapindex creates a...

Let’s Encrypt to Replace 200M Certificates a Day

Let’s Encrypt just announced an infrastructure makeover which means the open certificate authority CA is able to re-issue up to 200 million certificates in a 24-hour period, something the service said could be necessary in “some of the worst scenarios.” The upgrade comes a year after Let’s Encryp...

Kubernetes: Node Validation Admission does not observe all oldObject fields

Summary: The Validating Admission webhook for Node Objects is passing oldObject fields incorrectly on AdmissionReview.Request. It was identified initially in metadata.labels, but a list of impacted fields follows below: oldNode.Spec.PodCIDRs oldNode.Spec.ProviderID oldNode.Spec.ConfigSource...

Maintaining an Energy-Efficient Edge Platform

Over the past 20 years, we've seen a lot of growth at Akamai. When I started at Akamai, we used to have traffic peaks of almost 200 Mbps. From that fledgling startup, Akamai has now grown to such a scale that we almost doubled network capacity in 2020 and were able to serve peaks of almost 200...

UBUNTU-CVE-2020-15254

Crossbeam is a set of tools for concurrent programming. In crossbeam-channel before version 0.4.4, the bounded channel incorrectly assumes that Vec::fromiter has allocated capacity that same as the number of iterator elements. Vec::fromiter does not actually guarantee that and may allocate extra...

Security Vulnerabilities fixed in Firefox 82 — Mozilla

A use-after-free bug in the usersctp library was reported upstream. We assume this could have led to memory corruption and a potentially exploitable crash. In the crossbeam rust crate, the bounded channel incorrectly assumed that Vec::fromiter had allocated capacity that was the same as the numbe...

Is 97% Network Traffic Offload Interesting?

Sports, gaming, and other live events have the potential to overwhelm network capacity due to the sheer volume of traffic generated when large numbers of viewers or gamers engage. These "peak" events may only occur once a month or even once a year sports championships, election results, gaming...
