CWE-189Published: May 23, 2006· Updated: Jun 16, 2026
7.5
CVSS v3.1
Official Description
Multiple integer overflows in FreeType before 2.2 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via attack vectors related to (1) bdf/bdflib.c, (2) sfnt/ttcmap.c, (3) cff/cffgload.c, and (4) the read_lwfn function and a crafted LWFN file in base/ftmac.c. NOTE: item 4 was originally identified by CVE-2006-2493.
Technical Analysis
CVE-2006-1861 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.
