Detailsinfo

A vulnerability classified as critical has been found in Suricata up to 4.1.3. Affected is the function DecodeMPLS of the file decode-mpls.c. The manipulation as part of a Network Packet leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number for shim, an attacker can manipulate the control flow, such that the condition to leave the loop is true. After leaving the loop, the network packet has a length of 2 bytes. There is no validation of this length. Later on, the code tries to read at an empty position, leading to a crash.

The weakness was published 05/13/2019. This vulnerability is traded as CVE-2019-10050 since 03/25/2019. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

Upgrading to version 4.1.4 eliminates this vulnerability.
