User interaction is required to exploit this vulnerability in that the target must open a malicious file. By providing a malformed PNG file with an invialid uint32 CRC checksum, an attacker can cause an heap memory corruption. An attacker could leverage this to execute arbitrary code under the context of the application.   #####################################################################################   ===========   4) POC   ===========   (Theses files must be in the same folder for Bridge CC)   http://protekresearchlab.com/exploits/COSIG-2016-09-1.png http://protekresearchlab.com/exploits/COSIG-2016-09-2.png   https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/39430.zip   ###############################################################################
