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.
AnalysisAI
TeamViewer DEX Client versions before 26.1 contain an out-of-bounds read in the Content Distribution Service that enables remote attackers to leak stack memory and trigger denial of service without authentication. Successful exploitation could disclose memory contents useful for bypassing address space layout randomization and chaining with other vulnerabilities. No patch is currently available for this medium-severity flaw affecting Windows deployments.
