CVE-2023-29403: Fedoraproject Fedora

High severity, CVSS 7.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Fedoraproject Fedora: version 38 only
• Golang Go: before 1.19.10 (fixed in 1.19.10); from 1.20.0, before 1.20.5 (fixed in 1.20.5)
