Description Jan Lieskovsky 2011-02-27 19:38:57 UTC
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.

proposed patch

This patch fixes the bug by escaping line-feed and backslash and by using 2 * PATH_MAX + 16 for buffer size if PATH_MAX is defined.
