CVE-ID: CVE-2020-10938

CWE-ID: CWE-190

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the HuffmanDecodeImage in "magick/compress.c" file. A remote attacker can trigger integer overflow and execute arbitrary code on the target system, leading to heap-based buffer overflow.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
