Description Marcus Meissner 2018-06-21 06:36:30 UTC

CVE-2018-12327

Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an
attacker to achieve code execution or escalate to higher privileges via a long
string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is
unclear whether there are any common situations in which ntpq or ntpdc is used
with a command line from an untrusted source.

Comment 1 Marcus Meissner 2018-06-21 06:38:32 UTC

QA REPRODUCER:

/usr/sbin/ntpq -4 [`python -c 'print "A" * 300'`]

should not crash

also
/usr/sbin/ntpdc -4 [`python -c 'print "A" * 300'`]

should not crash

Comment 2 Marcus Meissner 2018-06-21 06:40:03 UTC

as the CVE entry said, that these are called with untrusted input is unlikely.

sle11 - not caught by overflow detection

sle12 and onwards: fstack-protector triggers and aborts the program

Comment 3 Reinhard Max 2018-09-11 10:57:01 UTC
