Description Pedro Sampaio 2017-09-15 19:03:29 UTC 
An exploitable buffer overflow vulnerability exists in the tag parsing functionality of LibOFX 0.9.11. A specially crafted OFX file can cause a write out of bounds resulting in a buffer overflow on the stack. An attacker can construct a malicious OFX file to trigger this vulnerability.
