Twas brillig at 16:32:03 when Slava Semushin did gyre and gimble:

SS> то невызов endpwent() чреват утечкой файлового дескриптора.
Невызов endpwent() чреват тем, что если в промежутке между getpwuid()
и endpwent() злоумышленик получит каким-либо образом доступ к памяти
процесса, то он имеет шансы прочитать содержимое /etc/passwd.
ps: а как этот вопрос относится к devel@? Может, лучше в sisyphus@
спрашивать?
