nss_db: Propagate ERANGE error if parse_line fails [BZ #19837] |
|
|
|
Reproducer (needs to run as root): |
|
|
|
perl -e \ |
|
'print "large:x:999:" . join(",", map {"user$_"} (1 .. 135))."\n"' \ |
|
>> /etc/group |
|
cd /var/db |
|
make |
|
getent -s db group |
|
|
|
After the fix, the last command should list the "large" group. |
|
|
|
The magic number 135 has been chosen so that the line is shorter than |
|
1024 bytes, but the pointers required to encode the member array will |
|
cross the threshold, triggering the bug. |
