VAR-202104-1827
Vulnerability from variot - Updated: 2024-11-23 20:33A vulnerability has been identified in APOGEE PXC Compact (BACnet) (All versions < V3.5.5), APOGEE PXC Compact (P2 Ethernet) (All versions < V2.8.20), APOGEE PXC Modular (BACnet) (All versions < V3.5.5), APOGEE PXC Modular (P2 Ethernet) (All versions < V2.8.20), Nucleus NET (All versions < V5.2), Nucleus Source Code (Versions including affected DNS modules), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). The DNS domain name record decompression functionality does not properly validate the pointer offset values. The parsing of malformed responses could result in a write past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to execute code in the context of the current process or cause a denial-of-service condition. The Nucleus NET module contains a series of standard-compliant network and communication protocols, drivers and utilities to provide full-featured network support in any embedded device.
The Siemens Nucleus product has an out-of-bounds write vulnerability. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements

Vulnerability from csaf_certbund - Published: 2021-04-15 22:00 - Updated: 2024-02-12 23:00In der DNS-Implementierung in weitgenutzten TCP/IP Stacks bestehen mehrere Schwachstellen, die sich in Server-Anwendungen, aber auch IoT und OT-Devices befinden. Sie basieren größtenteils auf Fehlern in der Kompressionsfunktion der DNS-Implementierung. Ein entfernter anonymer Angreifer kann diese Schwachstellen ausnutzen, um beliebigen Code mit Administratorrechten zur Ausführung zu bringen oder einen Denial of Service zu verursachen.
