| Doc Text: |
A flaw was found in libheif, a software library for decoding and encoding HEIF and AVIF image files. A remote attacker could exploit this by providing a specially crafted image file. This crafted file could cause the library to repeatedly process the same image data, leading to excessive use of the computer's processing power and memory. This could result in a Denial of Service (DoS), making the affected system unresponsive.
