Detailsinfo

A vulnerability was found in FreeRTOS-Plus-TCP up to 4.1.0. It has been rated as critical. This issue affects an unknown function of the component DNS Response Parser. The manipulation of the argument length with an unknown input leads to a buffer over-read vulnerability. Using CWE to declare the problem leads to CWE-126. The product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

FreeRTOS-Plus-TCP is a lightweight TCP/IP stack for FreeRTOS. FreeRTOS-Plus-TCP versions 4.0.0 through 4.1.0 contain a buffer over-read issue in the DNS Response Parser when parsing domain names in a DNS response. A carefully crafted DNS response with domain name length value greater than the actual domain name length, could cause the parser to read beyond the DNS response buffer. This issue affects applications using DNS functionality of the FreeRTOS-Plus-TCP stack. Applications that do not use DNS functionality are not affected, even when the DNS functionality is enabled. This vulnerability has been patched in version 4.1.1.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-38373 since 06/14/2024. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available.

Upgrading to version 4.1.1 eliminates this vulnerability. The upgrade is hosted for download at github.com.
