Published: 23 June 2022

Notes
| Author | Note |
|---|---|
| mdeslaur | pidgin in precise+ uses embedded libgadu |
| alexmurray | The various Ubuntu source packages listed against this CVE all contain an embedded copy of protobuf-c but they still needed to be triaged to determine if they actually use their own embedded copy or whether they link against the system libprotobuf-c |
| mdeslaur | in sudo, only used by sudo_logsrvd, setting priority to low |
| eslerm | sudo is patched and they sent PR to protobuf-c upstream |
