Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the function ext4xattr inodedecrefall not releasing iloc.bh properly, resulting in a leak of the...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the decodemaskimage function. An attacker can cause a heap buffer overflow by providing a crafted HEIF file containing a mask image where the iloc extent exceeds the allocated pixel buffer, leading to...
