GHSA-5W2F-HR95-2H6J
Vulnerability from github – Published: 2024-05-21 15:31 – Updated: 2024-12-26 18:30
VLAI
Details
In the Linux kernel, the following vulnerability has been resolved:
nexthop: Fix division by zero while replacing a resilient group
The resilient nexthop group torture tests in fib_nexthop.sh exposed a possible division by zero while replacing a resilient group [1]. The division by zero occurs when the data path sees a resilient nexthop group with zero buckets.
The tests replace a resilient nexthop group in a loop while traffic is forwarded through it. The tests do not specify the number of buckets while performing the replacement, resulting in the kernel allocating a stub resilient table (i.e, 'struct nh_res_table') with zero buckets.
This table should never be visible to the data path, but the old nexthop group (i.e., 'oldg') might still be used by the data path when the stub table is assigned to it.
Fix this by only assigning the stub table to the old nexthop group after making sure the group is no longer used by the data path.
Tested with fib_nexthops.sh:
Tests passed: 222 Tests failed: 0

Details
A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.

Vulnerability from github – Published: 2021-05-21 14:22 – Updated: 2024-10-30 23:18
VLAI
Summary
Division by 0 in `QuantizedMul`
Details
Impact
An attacker can trigger a division by 0 in tf.raw_ops.QuantizedMul:
import tensorflow as tf
x = tf.zeros([4, 1], dtype=tf.quint8)
y = tf.constant([], dtype=tf.quint8)
min_x = tf.constant(0.0)
max_x = tf.constant(0.0010000000474974513)
min_y = tf.constant(0.0)
max_y = tf.constant(0.0010000000474974513)
tf.raw_ops.QuantizedMul(x=x, y=y, min_x=min_x, max_x=max_x, min_y=min_y, max_y=max_y)
This is because the implementation does a division by a quantity that is controlled by the caller:
template <class T, class Toutput>
void VectorTensorMultiply(const T* vector_data, int32 vector_offset,
int64 vector_num_elements, const T* tensor_data,
int32 tensor_offset, int64 tensor_num_elements,
Toutput* output) {
for (int i = 0; i < tensor_num_elements; ++i) {
const int64 vector_i = i % vector_num_elements;
...
}
}
Patches
We have patched the issue in GitHub commit a1b11d2fdd1e51bfe18bb1ede804f60abfa92da6.
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.
