Internet Bug Bounty: [CVE-2020-27194] Linux kernel: eBPF verifier bug in `or` binary operation tracking function leads to LPE

CVE-2020-27194 is a eBPF verifier bug that allows an unprivileged attacker to create BPF socket filter programs that can read and write Out of Bounds, trough which an arbitrary kernel read write can be achieved. I'm taking the root cause explanation from the patch email: Simon reported an issue...

CVE-2020-15214

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger a write out bounds / segmentation fault if the segment ids are not sorted. Code assumes that the segment ids are in increasing order, using the last element of the tensor holding them to determine the...

CVE-2020-15211

In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indice...

PYSEC-2020-135

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to segmentidsdata can alter outputindex and then write to outside of outputdata...

CVE-2020-15212 Out of bounds access in tensorflow-lite

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to segmentidsdata can alter outputindex and then write to outside of outputdata...

CVE-2020-15214 Out of bounds write in tensorflow-lite

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger a write out bounds / segmentation fault if the segment ids are not sorted. Code assumes that the segment ids are in increasing order, using the last element of the tensor holding them to determine the...

Out of bounds access in tensorflow-lite

Impact In TensorFlow Lite models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor:...

Denial of service in tensorflow-lite

Impact In TensorFlow Lite models using segment sum can trigger a denial of service by causing an out of memory allocation in the implementation of segment sum. Since code uses the last element of the tensor holding them to determine the dimensionality of output tensor, attackers can use a very...

Segmentation fault in tensorflow-lite

Impact If a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. Patches We have patched the issue in d58c96946b and will release patch releases for all versions between 1.1...

Code injection

An issue was discovered on LG mobile devices with Android OS 7.0, 7.1, 7.2, 8.0, and 8.1 software. Applications with sensitive security settings such as the package verifier application mishandle unknown-source installations. The LG ID is LVE-SMP-190002 September 2020...

CVE-2020-25281

The CVE-2020-25281 entry concerns LG mobile devices running Android 7.x–8.1 where apps with sensitive security settings (e.g., the package verifier) mishandle unknown-source installations. Affected component/function relates to the installation pipeline for unknown sources. Underlying impact stat...

CVE-2020-8835

An out-of-bounds access flaw was found in the Linux kernel’s implementation of the eBPF code verifier, where an incorrect register bounds calculation while checking 32-bit instructions in an eBPF program occurs. This flaw allows an unprivileged user or process to execute eBPF programs to crash th...

Updated kernel packages fix security vulnerabilities

This update is based on upstream 5.5.14 and fixes at least the following security vulnerabilities: In the Linux kernel 5.3.10, there is a use-after-free read in the perftracelockacquire function related to include/trace/events/lock.h CVE-2019-19769. Manfred Paul discovered that the bpf verifier i...

DEBIAN-CVE-2020-8835

In the Linux kernel 5.5.0 and newer, the bpf verifier kernel/bpf/verifier.c did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the...
