Description Avinash Hanwate 2022-02-07 07:48:45 UTC

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.
