"A vulnerability has been discovered and corrected in rsyslog :

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
(CVE-2011-4623).

The updated packages have been patched to correct this issue."
