FKIE_CVE-2017-17935

Vulnerability from fkie_nvd - Published: 2017-12-27 17:08 - Updated: 2026-06-17 01:11
Severity
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
The File_read_line function in epan/wslua/wslua_file.c in Wireshark through 2.2.11 does not properly strip '\n' characters, which allows remote attackers to cause a denial of service (buffer underflow and application crash) via a crafted packet that triggers the attempted processing of an empty line.
