Description

The version of Subversion Server installed on the remote host is prior to version 1.8.2. It is, therefore, affected by multiple vulnerabilities :

  • A repository corruption vulnerability related to

vulnerabilities :

  - A repository corruption vulnerability related to

    and handling packed revision properties editing.

  - A symlink privilege escalation vulnerability in

    --pidfile option is used. The option creates temporary
    files insecurely, and may allow a local attacker to use
    a symlink attack against a pid file to gain elevated
    privileges. (CVE-2013-7393)");
