CVE-2023-29403

Published: 8 June 2023

On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors closed, opening any files can result in unexpected content being read or written with elevated privileges. Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents of its registers.

Notes

Packages built using golang need to be rebuilt once the
vulnerability has been fixed. This CVE entry does not
list packages that need rebuilding outside of the main
repository or the Ubuntu variants with PPA overlays.
