Christey" <coley@...us.mitre.org>, Chris Wright <chrisw@...hat.com>, Greg KH <greg@...ah.com> Subject: CVE request: kernel: exit_notify: kill the wrong capable(CAP_KILL) check A malicious application can execute a setuid binary before exit. This would mean that we will not reset the ->exit_signal to SIGCHLD unless the binary drops CAP_KILL. https://bugzilla.redhat.com/show_bug.cgi?id=493771 http://git.kernel.org/linus/432870dab85a2f69dc417022646cb9a70acf7f94 Chris/Greg, we probably need this in -stable. Thanks, Eugene -- Eugene Teo, RHCA, RHCSS / Red Hat Security Response Team
