Summary:

Several security issues were fixed in the Apache HTTP Server.

Software Description:
- apache2: Apache HTTP server

Details:

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 MER=
GE
requests. A remote attacker could use this issue to cause the server to
stop responding, resulting in a denial of service. (CVE-2013-1896)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.04:
apache2.2-common 2.2.22-6ubuntu5.1

apache2.2-common 2.2.22-6ubuntu2.3
