mount and umount in util-linux and loop-aes-utils call the setuid and setgid functions in the wrong order and do not check the return values, which might allow attackers to gain privileges via helpers such as mount.nfs.
CWE-696
CVE-2007-1588
server.cpp in MyServer 0.8.5 calls Process::setuid before calling Process::setgid and thus does not properly drop privileges, which might allow remote attackers to execute CGI programs with unintended privileges.
