Subject: CVE Request -- rsyslog -- DoS due integer signedness error while
 extending rsyslog counted string buffer

An integer signedness error, leading to heap based buffer overflow was found in
the way the imfile module of rsyslog, an enhanced system logging and kernel
message trapping daemon, processed text files larger than 64 KB. When the
imfile rsyslog module was enabled, a local attacker could use this flaw to
cause denial of service (rsyslogd daemon hang) via specially-crafted message,
to be logged.
