CVE-2020-27738

https://notcve.org/view.php?id=CVE-2020-27738

A 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), Nucleus ReadyStart V3 (All versions < V2017.02.3), Nucleus ReadyStart V4 (All versions < V4.1.0), Nucleus Source Code (Versions including affected DNS modules), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), 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 read access past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition. Se ha identificado una vulnerabilidad en Nucleus NET (Todas las versiones), Nucleus ReadyStart V3 (Todas las versiones anteriores a V2017.02.3), Nucleus ReadyStart V4 (Todas las versiones anteriores a V4.1.0), Nucleus Source Code (Versiones que incluyen los módulos DNS afectados), SIMOTICS CONNECT 400 (Todas las versiones anteriores a V0.5.0.0). • https://cert-portal.siemens.com/productcert/pdf/ssa-180579.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-669158.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-705111.pdf • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-788: Access of Memory Location After End of Buffer •

A 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), Nucleus ReadyStart V3 (All versions < V2017.02.3), Nucleus ReadyStart V4 (All versions < V4.1.0), Nucleus Source Code (Versions including affected DNS modules), SIMOTICS CONNECT 400 (All versions < V0.5.0.0), TALON TC Compact (BACnet) (All versions < V3.5.5), TALON TC Modular (BACnet) (All versions < V3.5.5). The DNS response parsing functionality does not properly validate various length and counts of the records. The parsing of malformed responses could result in a read past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition or leak the memory past the allocated structure.
