<product type="ebuild">syslog-ng</product>
<announced>December 29, 2007</announced>
<revised>December 29, 2007: 01</revised>

Syslog-ng is a flexible and scalable system logger.
Oriol Carreras reported a NULL pointer dereference in the
log_msg_parse() function when processing timestamps without a
terminating whitespace character.
<impact type="normal">
A remote attacker could send a specially crafted event to a vulnerable
Syslog-ng server, resulting in a crash.
There is no known workaround at this time.
All Syslog-ng users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-admin/syslog-ng-2.0.6&quot;</code>
