Lifecycle Timeline
2Description
An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows an attacker on the adjacent network to cause information disclosure or denial-of-service via a special crafted packet. The leaked memory could be used to bypass ASLR and facilitate further exploitation.
Analysis
Information disclosure and denial-of-service in TeamViewer DEX Client versions before 26.1 allows adjacent network attackers to trigger an out-of-bounds read via specially crafted packets, potentially leaking sensitive memory that could be leveraged to bypass ASLR protections. Affected Windows systems running the NomadBranch.exe content distribution service are vulnerable to attacks requiring only network proximity, with no authentication or user interaction needed.
