NVD Description

Note: Versions mentioned in the description apply only to the upstream gerbv package and not the gerbv package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An information disclosure vulnerability exists in the pick-and-place rotation parsing functionality of Gerbv 2.7.0 and dev (commit b5f1eacd), and Gerbv forked 2.8.0. A specially-crafted pick-and-place file can exploit the missing initialization of a structure to leak memory contents. An attacker can provide a malicious file to trigger this vulnerability.
