EF Commander ISO pathname buffer overflow

efcommander-iso-pathname-bo (31365)

High Risk

Description:

EF Commander is vulnerable to a stack-based buffer overflow, caused by improper bounds checking of ISO image files. By sending a specially-crafted ISO image file containing an overly long pathname, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash, if the attacker could persuade the victim to open the malicious file.
