CVE-2011-1155 logrotate: DoS due improper escaping of file names within 'write state' action
Last modified: 2015-07-30 09:13:30 EDT
A denial of service flaw was found in the way the logrotate utility
performed arguments sanitization, when performing the 'write state'
action. A local attacker could use this flaw to cause abort in
subsequent logrotate runs via a specially-crafted log file name.
