Summary

A flaw was found in FreeType, specifically within its CID font loader. A remote attacker could exploit this vulnerability by tricking a user into opening content that embeds or references a specially crafted CID-keyed font. This crafted font can cause repeated allocations and decryptions of subroutine data across multiple font dictionaries, leading to excessive memory and CPU consumption. This can result in a denial of service (DoS) for the application or service processing the font, potentially causing it to hang or terminate.
