Title
Out-of-bounds read vulnerability in Content Distribution Service
Summary
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 a remote attacker to leak stack memory and cause a denial of service via a crafted request. The leaked stack memory could be used to bypass ASLR remotely and facilitate exploitation of other vulnerabilities on the affected system.
