Описание
In the Linux kernel, the following vulnerability has been resolved:
tipc: Return non-zero value from tipc_udp_addr2str() on error
tipc_udp_addr2str() should return non-zero value if the UDP media
address is invalid. Otherwise, a buffer overflow access can occur in
tipc_media_addr_printf(). Fix this by returning 1 on an invalid UDP
media address.
A flaw was found in Linux kernel tipc. tipc_udp_addr2str() does not return a nonzero value when UDP media address is invalid, which can result in a buffer overflow in tipc_media_addr_printf().
Отчет
This vulnerability exists in the kernel's TIPC networking code. This functionality is typically only used for low-latency interprocess communication between nodes in a cluster computer. Additionally, an attacker must be able to create a UDP connection with an invalid address. Since this vulnerability is only applicable to systems using TIPC and exploitation requires an attacker to already have significant privileges on the target system, Red Hat assesses this flaw as having Moderate impact. Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-393: Return of Wrong Status Code vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. The platform enforces hardening guidelines to apply the most restrictive settings necessary for operational needs, while baseline configurations maintain secure system and software states. A defense-in-depth monitoring strategy includes perimeter firewalls and endpoint protection services that detect and respond to threats in real time, helping prevent or limit exploitation attempts. Robust input validation and error handling ensure all user inputs are thoroughly validated, supporting consistent and secure system responses.
