Description
A numeric truncation error, leading to a heap-based buffer overflow, was
found in the way the rsyslog imfile module processed text files containing
long lines. An attacker could use this flaw to crash the rsyslogd daemon
or, possibly, execute arbitrary code with the privileges of rsyslogd, if
they are able to cause a long line to be written to a log file that
rsyslogd monitors with imfile. The imfile module is not enabled by default.
(CVE-2011-4623)
