Debian Linux Security Advisory 5774-1 - It was discovered that ruby-saml, a SAML library implementing the client side of a SAML authorization, does not properly verify the signature of the SAML Response, which could result in bypass of authentication in an application using the ruby-saml library.

There exists a use after free vulnerability in Reverb. Reverb supports the VARIANT datatype, which is supposed to represent an arbitrary object in C++. When a tensor proto of type VARIANT is unpacked, memory is first allocated to store the entire tensor, and a ctor is called on each instance. Afterwards, Reverb copies the content in tensor_content to the previously mentioned pre-allocated memory, which results in the bytes in tensor_content overwriting the vtable pointers of all the objects which were previously allocated. Reverb exposes 2 relevant gRPC endpoints: InsertStream and SampleStream. The attacker can insert this stream into the server’s database, then when the client next calls SampleStream they will unpack the tensor into RAM, and when any method on that object is called (including its destructor) the attacker gains control of the Program Counter. We recommend upgrading past git commit  https://github.com/google-deepmind/reverb/commit/6a0dcf4c9e842b7f999912f792aaa6f6bd261a2...

A North Korea-linked cyber-espionage group has been observed leveraging job-themed phishing lures to target prospective victims in energy and aerospace verticals and infect them with a previously undocumented backdoor dubbed MISTPEN. The activity cluster is being tracked by Google-owned Mandiant under the moniker UNC2970, which it said overlaps with a threat group known as TEMP.Hermit, which is

Any vulnerability in an RTOS has the potential to affect many devices across multiple industries.

The threat actors behind the BlackByte ransomware group have been observed likely exploiting a recently patched security flaw impacting VMware ESXi hypervisors, while also leveraging various vulnerable drivers to disarm security protections. "The BlackByte ransomware group continues to leverage tactics, techniques, and procedures (TTPs) that have formed the foundation of its tradecraft since its

In recent investigations, Talos Incident Response has observed the BlackByte ransomware group using techniques that depart from their established tradecraft. Read the full analysis.
