cff/cf2intrp.c in the CFF CharString interpreter in FreeType before 2.5.4 proceeds with additional hints after the hint mask has been computed, which allows remote attackers to execute arbitrary code. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.

Technical ContextAI · show details
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. cff/cf2intrp.c in the CFF CharString interpreter in FreeType before 2.5.4 proceeds with additional hints after the hint mask has been computed, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted OpenType font. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2240. Affected products include: Oracle Solaris, Freetype, Fedoraproject Fedora, Opensuse, Canonical Ubuntu Linux. Version information: before 2.5.4.

Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
