CVE-2011-1488: Debian Linux

Medium severity, CVSS 5.5. EPSS: 0.5% chance of exploitation in the next 30 days.

A memory leak in rsyslog before 5.7.6 was found in the way deamon processed log messages are logged when $RepeatedMsgReduction was enabled. A local attacker could use this flaw to cause a denial of the rsyslogd daemon service by crashing the service via a sequence of repeated log messages sent within short periods of time.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only; version 10.0 only
• Opensuse Opensuse: version 11.4 only
• Rsyslog Rsyslog: before 5.7.6 (fixed in 5.7.6)
