AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Wireshark versions prior to 2.2.12

Description The issue is related to the File read line function in epan/wslua/wslua file.c, which does not properly strip ' ' characters. This allows remote attackers to cause a denial of service, resulting in a buffer underflow and application crash, via a crafted packet that triggers the attempted processing of an empty line.

Recommendations For Wireshark versions prior to 2.2.12, update to version 2.2.12 or later to resolve the issue. As a temporary workaround, consider restricting the processing of crafted packets to minimize the risk of exploitation.
