Package: finger
Version: 0.17-6
Hi folks,
finger does a core dump on my machine. Starting it with
'strace -f finger' I get
:
:
open("/etc/passwd", O_RDONLY) = 3
fcntl64(3, F_GETFD) = 0
fcntl64(3, F_SETFD, FD_CLOEXEC) = 0
fstat64(3, {st_mode=S_IFREG|0644, st_size=1137, ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40015000
_llseek(3, 0, [0], SEEK_CUR) = 0
read(3, "root:fxiEqFrcCE4HKQ:0:0:root:/roo"..., 4096) = 1137
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
The problem seems to be related to the last line in
/etc/passwd: Its just a '+'. Thats the traditional way
to include NIS. If I remove the '+', then the problem is
gone.
Of course I know nsswitch.conf and how to configure it. But
nevertheless, finger shouldn't die with a core dump.
Regards
Harri
