5.0
Medium
| Vector | AV:N/AC:L/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
rsyslog versions 4.6.x through 4.6.7
rsyslog versions 5.2.0 through 5.8.4
Description
The issue is related to a stack-based buffer overflow in the
parseLegacySyslogMsg function in tools/syslogd.c in rsyslogd. This might allow remote attackers to cause a denial of service (application exit) via a long TAG in a legacy syslog message. The vulnerability can be exploited remotely and may lead to disruption of protected information availability.Recommendations
For rsyslog versions 4.6.x through 4.6.7, update to version 4.6.8 or later.
For rsyslog versions 5.2.0 through 5.8.4, update to a version later than 5.8.4.
As a temporary workaround, consider restricting access to the
parseLegacySyslogMsg function until a patch is available.Exploit
