Description Thibault Guittet 2026-08-11 07:41:18 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A flaw was found in svxlink's LocationInfo/APRS functionality. In AprsTcpClient.cpp, updateQsoStatus() formats a remote EchoLink station's callsign and info into a fixed 80-byte stack buffer using sprintf. A long callsign or info string overflows the buffer, potentially enabling code execution. The overflow has existed since 2010. Fixed in version 26.05.1.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
