CVE-2016-3091 Diego log encoding vulnerability




Cloud Foundry Foundation

Versions Affected
  • Diego-release versions 0.1468.0 through 0.1470.0

Due to how Diego handles breaking up large log streams on UTF-8 boundaries, it is possible to cause a denial of service on a Cloud Foundry installation with an app outputting malformed UTF-8 sequences.
