Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
gpsd versions 2.90 to 3.17 and microjson versions 1.0 to 1.3, an open source project, allow a stack-based buffer overflow, which may allow remote attackers to execute arbitrary code on embedded platforms via traffic on Port 2947/TCP or crafted JSON inputs.
