USN-1903-1: Apache HTTP Server vulnerabilities

15 July 2013

Several security issues were fixed in the Apache HTTP Server.




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)

Update instructions

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

Ubuntu 13.04
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
