Description Jan Lieskovsky 2008-12-15 17:49:47 UTC
A denial of service flaw was reported in the upstream Rsyslog syslogd
support. A non-permitted sender could send a message to the imudp plugin,
which would reply by emitting a message, each time such an request
was made. This could allow an attacker to cause a DoS (excessive disk space
consummation).

Comment 1 Jan Lieskovsky 2008-12-15 17:51:30 UTC
This issue does NOT affect the version of the Rsyslog package, as shipped
with Red Hat Enterprise Linux 5.

This issue affects the versions of the Rsyslog package, as shipped
with Fedora releases of 9, 10 and devel (Fedora release of 8 is not
affected).

Comment 2 Tomas Heinrich 2008-12-15 18:26:14 UTC
This issue affects versions 3.20.1 and 3.21.8.
The current versions in Fedora 9, 10 and devel are 3.20.2, 3.21.9 and 3.21.9, respectively.

The referenced patch should be against version 3.20.1.

Comment 3 Fedora Update System 2008-12-17 09:51:19 UTC
rsyslog-3.20.2-2.fc9 has been submitted as an update for Fedora 9.
http://admin.fedoraproject.org/updates/rsyslog-3.20.2-2.fc9

Comment 4 Tomas Hoger 2008-12-17 10:18:22 UTC
CVE id CVE-2008-5618 was assigned to this issue:

imudp in rsyslog 4.x before 4.1.2, 3.21 before 3.21.9 beta, and 3.20
before 3.20.2 generates a message even when it is sent by an
unauthorized sender, which allows remote attackers to cause a denial
of service (disk consumption) via a large number of spurious messages.

Comment 5 Fedora Update System 2008-12-21 08:38:18 UTC
rsyslog-3.20.2-2.fc9 has been pushed to the Fedora 9 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 6 Fedora Update System 2008-12-21 08:44:53 UTC
rsyslog-3.21.9-1.fc10 has been pushed to the Fedora 10 stable repository.  If problems still persist, please make note of it in this bug report.
