Vulnerability Details

CVEID:CVE-2020-5313
**DESCRIPTION:**Python Pillow is vulnerable to a buffer overflow, caused by improper bounds checking by libImaging/FliDecode.c. By persuading a victim to open a specially-crafted FLI file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/173926 for the current score.
