critical Nessus Plugin ID 141403
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has kernel packages installed that are affected by multiple vulnerabilities:

- base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)

- In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL kernel packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
