https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259822 Bug ID: 259822 Summary: Exim: 4.95 taking SIGSEGVs on 12.2 Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: j2465@wizmail.org FreeBSD 12.2 - upstream project has reports of segvs from exim 4.95 and is debugging the issue. So far, we know we're getting fd values *well* over 1024, and since we use select() this is very likely to smash the stack. Possibly this will only occur on a reasonably-loaded server system, but any that is running long enough will be vulnerable. Presumably the change in behaviour is due to the FreeBSD kernel (no longer handing out the lowest usable fd, when creating a new handle?) and not actually due to the Exim version. -- You are receiving this mail because: You are the assignee for the bug.
