CVE-2011-4597
The SIP over UDP implementation in Asterisk Open Source 1.4.x before
1.4.43, 1.6.x before 1.6.2.21, and 1.8.x before 1.8.7.2 uses different
port numbers for responses to invalid requests depending on whether a
SIP username exists, which allows remote attackers to enumerate
usernames via a series of requests.

CVE-2011-4598
channels/chan_sip.c in Asterisk Open Source 1.6.2.x before 1.6.2.21
and 1.8.x before 1.8.7.2, when automon is enabled, allows remote
attackers to cause a denial of service (NULL pointer dereference and
daemon crash) via a crafted sequence of SIP requests.";
