CVE-2013-1048

Status: ModifiedMedium (4.6)—

The Debian apache2ctl script in the apache2 package squeeze before 2.2.16-6+squeeze11, wheezy before 2.2.22-13, and sid before 2.2.22-13 for the Apache HTTP Server on Debian GNU/Linux does not properly create the /var/lock/apache2 lock directory, which allows local users to gain privileges via an unspecified symlink attack.
