This flaw enables a local attacker to execute arbitrary code on a vulnerable system. The vulnerability arises from insufficient bounds checking when processing input, allowing an attacker to overwrite critical parts of the stack. Successful exploitation requires the attacker to craft a malicious input file specifically designed to trigger the overflow. The impact of this…</p> highadvisorycve-2019-25634buffer-overflowseh-overwritecode-execution
