Details

Hugo van Kemenade discovered that Pillow was not properly performing
bounds checks when processing an ICC file, which could lead to a buffer
overflow. If a user or automated system were tricked into processing a
specially crafted ICC file, an attacker could possibly use this issue
to cause a denial of service or execute arbitrary code.
