Official Description

JPEGDEC commit be4843c was discovered to contain a global buffer overflow via JPEGDecodeMCU at /src/jpeg.inl.

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability is triggered when the JPEGDecodeMCU function processes a malicious JPEG file. The global buffer overflow occurs due to improper bounds checking, allowing an attacker to write data beyond the allocated buffer size.
