CVSS v3.1
7.5
High
| Vector | 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 2.0.0 through 2.0.12
Wireshark versions 2.2.0 through 2.2.6
Description
The issue arises from the MSNIP dissector misusing a NULL pointer, which can be exploited. This was resolved by validating an IPv4 address in the epan/dissectors/packet-msnip.c file.
Recommendations
For Wireshark versions 2.0.0 through 2.0.12, update to a version where the MSNIP dissector properly validates IPv4 addresses to prevent the misuse of a NULL pointer.
For Wireshark versions 2.2.0 through 2.2.6, update to a version where the MSNIP dissector properly validates IPv4 addresses to prevent the misuse of a NULL pointer.
Fix
NULL Pointer Dereference
