The weakness exists in ofx_proc_file in ofx_preproc.cpp due to a boundary error. A remote attacker can trick the victim into opening a specially crafted file, as demonstrated by an ofxdump call, trigger heap-based buffer over-read and cause the service to crash.
2) Out-of-bounds write (CVE-ID: CVE-2017-2816)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in the tag parsing functionality due to out-of-bounds write when handling malicious input. A remote attacker can trick the victim into opening a specially crafted OFX file, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
3) Memory corruption (CVE-ID: CVE-2017-2920)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists in the .svg parsing functionality of Computerinsel PhotoLine due to boundary error.
