"It was discovered that the mod_rewrite module incorrectly sanitized
non- printable characters before writing data to log files. A remote
attacker could possibly use this flaw to execute arbitrary commands by
injecting escape sequences in the log file. (CVE-2013-1862)

It was discovered that the mod_dav module incorrectly handled certain
MERGE requests. A remote attacker could use this issue to cause the
server to stop responding, resulting in a denial of service.
(CVE-2013-1896).
