Description
This security bulletin contains information about 1 vulnerability.
1) Heap-based buffer over-read (CVE-ID: CVE-2017-14731)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
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.
