CVE-2009-0028

First published: Wed Jan 14 2009(Updated: )

From Chris Evans: It's a relatively minor signal issue where a child can send its parent process an arbitrary signal, even if the parent has a totally separate real and effective user id. This could be a nuisance in the case where long-running root daemons spawn direct child processes owned by untrusted users [*]. There may even be worse consequences if privileged processes have weak signal handling code for signals not normally triggerable by untrusted users.
