>Description:
When using FreeBSD 5.x as a NIS Client and the server is using
passwd.adjunct any program which call getpw*, generate a core dump.
(bug in libc)
>How-To-Repeat:
This simple test can be used to generate the core dump.
#include <stdio.h>
#include <pwd.h>
int main ()
{
struct passwd *pw = getpwuid( UID );
printf( "%s\n", (pw) ? pw->pw_name : "none" );
}
where UID is any user defined in NIS passwd and passwd.adjunct map.
Also doing a "ls -l FILE" where FILE is owned by a NIS user leads to
a core dump.
>Fix:
Patch /usr/src/lib/libc/gen/getpwent.c
diff getpwent.c getpwent.c-1.83.c
