CVE-2022-23476 (nokogiri)

Read Time:33 Second

Nokogiri is an open source XML and HTML library for the Ruby programming language. Nokogiri `1.13.8` and `1.13.9` fail to check the return value from `xmlTextReaderExpand` in the method `Nokogiri::XML::Reader#attribute_hash`. This can lead to a null pointer exception when invalid markup is being parsed. For applications using `XML::Reader` to parse untrusted inputs, this may potentially be a vector for a denial of service attack. Users are advised to upgrade to Nokogiri `>= 1.13.10`. Users may be able to search their code for calls to either `XML::Reader#attributes` or `XML::Reader#attribute_hash` to determine if they are affected.

Smashing Security podcast #301: AI chatbot or the start of Skynet? Eufy privacy, and hot desks

Read Time:23 Second

An AI chatbot is causing a stir – both impressing and terrifying users in equal measure. A security researcher discovers that a “smart” cam that doesn’t use the internet is err.. using the internet. And university students revolt over under-the-belt surveillance.

All this and much more is discussed in the latest edition of the award-winning “Smashing Security” podcast by computer security veterans Graham Cluley and Carole Theriault, joined this week by Host Unknown’s Thom Langford.

CVE-2022-23471

Read Time:44 Second

containerd is an open source container runtime. A bug was found in containerd’s CRI implementation where a user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal resize events if a TTY is requested. If the user’s process fails to launch due to, for example, a faulty command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak. Kubernetes and crictl can both be configured to use containerd’s CRI implementation and the stream server is used for handling container IO. This bug has been fixed in containerd 1.6.12 and 1.5.16. Users should update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted images and commands are used and that only trusted users have permissions to execute commands in running containers.
