Package: sympa Version: 6.2.16~dfsg-3+deb9u3 Severity: important Dear Maintainer(s),
since applying the security update from 6.2.16~dfsg-3+deb9u2 to 6.2.16~dfsg-3+deb9u3 I found some troubles with the session handling, i.e. the web server reports 2020/10/13 11:59:18 [error] 2123#2123: *3525 FastCGI sent in stderr: "Use of uninitialized value in string ne at /usr/share/sympa/lib/Sympa/Se ssion.pm line 406. Use of uninitialized value $remote_addr in string ne at /usr/share/sympa/lib/Sympa/Session.pm line 406" while reading upstream, client: 192.16 8.100.2, server: lists.welcomes-you.com, request: "POST /sympa HTTP/1.0", upstream: "fastcgi://unix:/run/fcgiwrap.socket:", host: "FQDN", referrer: "https://FQDN/sympa"; My configuration may be a bit "nasty" and may contribute here: The external https access to sympa is TLS terminated by nginx acting as a reverse proxy which then sends the requests via a virtual bridge to the container where sympa is running. After comparing the changes between u2 and u3 I fear this change here char *myenvp[] = { "IFS= \t\n", "PATH=/bin:/usr/bin", NULL }; [..] - return execve(WWSYMPA,argv,envp); + return execve(WWSYMPA, argv, myenvp); to the fcgi wrapper may cause the nginx set variable $ENV{'REMOTE_ADDR'} not to be set and thus session handling will not work anymore.
