- CWE-908 - Use of Uninitialized Resource
Summary
A certain crafted HTTP packet can trigger an uninitialized function pointer deference vulnerability in the Packet Forwarding Engine manager (fxpc) on all EX, QFX and MX Series devices in a Virtual Chassis configuration. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code execution. This issue only occurs when the crafted packet it destined to the device. Affected releases are Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D47 on EX and QFX Virtual Chassis Platforms; 15.1 versions prior to 15.1R7-S3 all Virtual Chassis Platforms 15.1X53 versions prior to 15.1X53-D50 on EX and QFX Virtual Chassis Platforms.

- CWE-908 - {"":"Use of Uninitialized Resource"}
Summary
In Tensorflow before versions 2.2.1 and 2.3.1, the implementation of `dlpack.to_dlpack` can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor. However, there is nothing stopping users from passing in a Python object instead of a tensor. The uninitialized memory address is due to a `reinterpret_cast` Since the `PyObject` is a Python object, not a TensorFlow Tensor, the cast to `EagerTensor` fails. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.

- CWE-908 - Use of Uninitialized Resource
Summary
In affected versions of TensorFlow under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers be filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.

Summary
There's a flaw in binutils /opcodes/tic4x-dis.c. An attacker who is able to submit a crafted input file to be processed by binutils could cause usage of uninitialized memory. The highest threat is to application availability with a lower threat to data confidentiality. This flaw affects binutils versions prior to 2.34.

- CWE-908 - Uninitialized Resource -> CWE-824 Uninitialized Pointer
Summary
A vulnerability was found in ewxrjk sftpserver. It has been declared as problematic. Affected by this vulnerability is the function sftp_parse_path of the file parse.c. The manipulation leads to uninitialized pointer. The real existence of this vulnerability is still doubted at the moment. The name of the patch is bf4032f34832ee11d79aa60a226cc018e7ec5eed. It is recommended to apply a patch to fix this issue. The identifier VDB-216205 was assigned to this vulnerability. NOTE: In some deployment models this would be a vulnerability. README specifically warns about avoiding such deployment models.

CWE
- CWE-908 - Use of Uninitialized Resource
Summary
An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process’s memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222 4.19.177 5.4.99 5.10.17 5.11

CWE
- CWE-908 - Use of Uninitialized Resource
Summary
TensorFlow is an end-to-end open source platform for machine learning. The implementation of `tf.raw_ops.FractionalMaxPoolGrad` triggers an undefined behavior if one of the input tensors is empty. The code is also vulnerable to a denial of service attack as a `CHECK` condition becomes false and aborts the process. The implementation(https://github.com/tensorflow/tensorflow/blob/169054888d50ce488dfde9ca55d91d6325efbd5b/tensorflow/core/kernels/fractional_max_pool_op.cc#L215) fails to validate that input and output tensors are not empty and are of the same rank. Each of these unchecked assumptions is responsible for the above issues. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

"value": "TensorFlow is an end-to-end open source platform for machine learning. The implementation of `tf.raw_ops.FractionalMaxPoolGrad` triggers an undefined behavior if one of the input tensors is empty. The code is also vulnerable to a denial of service attack as a `CHECK` condition becomes false and aborts the process. The implementation(https://github.com/tensorflow/tensorflow/blob/169054888d50ce488dfde9ca55d91d6325efbd5b/tensorflow/core/kernels/fractional_max_pool_op.cc#L215) fails to validate that input and output tensors are not empty and are of the same rank. Each of these unchecked assumptions is responsible for the above issues. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range."

Mitigation
Phase: Implementation
Description:
- Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Phase: Implementation
Description:
- Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Phase: Implementation
Description:
- Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Phase: Build and Compilation
Description:
- Run or compile the product with settings that generate warnings about uninitialized variables or data.
