Technical description

A Null Pointer Dereference vulnerability exits in ffjpeg d5cfd49 (2021-12-06) in bmp_load(). When the size information in metadata of the bmp is out of range, it returns without assign memory buffer to `pb->pdata` and did not exit the program. So the program crashes when it tries to access the pb->data, in jfif_encode() at jfif.c:763. This is due to the incomplete patch for CVE-2020-13438.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
