+IRSSI-SA-2017-07 Irssi Security Advisory [1]
+============================================
+CVE-2017-10965, CVE-2017-10966.
+
+Description
+-----------
+
+Two vulnerabilities have been located in Irssi.
+
+(a) When receiving messages with invalid time stamps, Irssi would try
+    to dereference a NULL pointer. Found by Brian 'geeknik' Carpenter
+    of Geeknik Labs. (CWE-690)
+
+    CVE-2017-10965 [2] was assigned to this bug
+
+(b) While updating the internal nick list, Irssi may incorrectly use
+    the GHashTable interface and free the nick while updating it. This
+    will then result in use-after-free conditions on each access of
+    the hash table. Found by Brian 'geeknik' Carpenter of Geeknik
+    Labs. (CWE-416 caused by CWE-227)
+
+    CVE-2017-10966 [3] was assigned to this bug
+
+
+Impact
+------
+
+(a) May result in denial of service (remote crash).
+
+(b) Undefined behaviour.
+
+
+Affected versions
+-----------------
+
+All Irssi versions that we observed.
+
+
+Fixed in
+--------
+
+Irssi 1.0.4
+
+
+Recommended action
+------------------

+Upgrade to Irssi 1.0.4. Irssi 1.0.4 is a maintenance release in the
+1.0 series, without any new features.
+
+After installing the updated packages, one can issue the /upgrade
+command to load the new binary. TLS connections will require
+/reconnect.
+
+
+Mitigating facts
