CVE-2026-56362

A heap-buffer-overflow read in ImageMagick's OpenPixelCache occurs when image channel metadata updates before memory allocation. Attackers can trigger this via memory and disk allocation failures to disclose sensitive information. Mitigation Isolate ImageMagick tasks by running them inside...

glibc: glibc: Heap Buffer Overflow in `scanf` with `%mc` format specifier and large width

A flaw was found in glibc GNU C Library. This vulnerability occurs when an application uses the scanf family of functions with a %mc format specifier, which is used for dynamically allocating memory for character input, and provides an explicit width greater than 1024. This specific combination c...

PYSEC-2026-3258 Integer overflow leading to crash in Tensorflow

Impact The implementation of SparseCountSparseOutput can be made to crash a TensorFlow process by an integer overflow whose result is then used in a memory allocation: python import tensorflow as tf import numpy as np tf.rawops.SparseCountSparseOutput indices=1,1, values=2, denseshape=2 31, 2 32,...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the compile function. An attacker can cause excessive memory consumption by supplying a large comma-separated selector list, leading to process termination or degraded system...

CVE-2026-31984

A denial-of-service vulnerability caused by unbounded resource allocation was discovered in the audit logging functionality, due to a missing size limit on input recorded into audit entries. An unauthenticated attacker can submit requests containing excessively large input that is recorded into...
