5.0
CVSS v3.1
Official Description
ftutil.c in Freetype before 2.2 allows remote attackers to cause a denial of service (crash) via a crafted font file that triggers a null dereference.
Technical Analysis
CVE-2006-2661 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2006-2661. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
