Re: CVE request for buffer overflow in ppp

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

The process id is used in rc_mksid to generate a pseudo-unique string,
assuming that the hex representation of the pid will be at most 4
characters (FFFF). __sprintf_chk(), used when compiling with
optimization levels greater than 0 and FORTIFY_SOURCE, detects the
buffer overflow and makes pppd crash.

the bug occurs if pppd's pid is greater than 65535. The number of
running processes is irrelevant.

Use CVE-2015-3310.
