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

ofx_proc_file in ofx_preproc.cpp in LibOFX 0.9.12 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file, as demonstrated by an ofxdump call.
