1ppp: Buffer overflow in radius plugin
2
3From: https://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;bug=782450

5Upstream-Status: Backport
6
7On systems with more than 65535 processes running, pppd aborts when
8sending a "start" accounting message to the RADIUS server because of a
9buffer overflow in rc_mksid.
10
11The process id is used in rc_mksid to generate a pseudo-unique string,
12assuming that the hex representation of the pid will be at most 4
13characters (FFFF). __sprintf_chk(), used when compiling with
14optimization levels greater than 0 and FORTIFY_SOURCE, detects the
15buffer overflow and makes pppd crash.
16
17The following patch fixes the problem.
