critical Nessus Plugin ID 149070
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 device is missing a vendor-supplied security patch.

Description

Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

Impact

An attacker could cause a denial of service (DoS) or arbitrary code executionif you use cURL to transfer data to or from a Trivial File Transport Protocol (TFTP) serverand set the blksize (block size) option to a value below 504 (the default value is 512). Setting a smaller block size than the default should be rare as the primary use case for changing the block size is to make it larger.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K41523201.
