commit 240ceafed7a00af8571d56db67a6b8854e418106
Author: Florian Weimer <fweimer@redhat.com>
Date: Tue Mar 29 11:27:32 2016 +0200
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.
(cherry picked from commit a6033052d08027f745867e5e346852da1959226c)
