Debian DSA-2118-1 : subversion - logic flaw

medium Nessus Plugin ID 49815

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Kamesh Jayachandran and C. Michael Pilat discovered that the mod_dav_svn module of Subversion, a version control system, is not properly enforcing access rules which are scope-limited to named repositories. If the SVNPathAuthz option is set to 'short_circuit' set this may enable an unprivileged attacker to bypass intended access restrictions and disclose or modify repository content.

Solution

Upgrade the subversion packages.

As a workaround it is also possible to set SVNPathAuthz to 'on' but be advised that this can result in a performance decrease for large repositories.

For the stable distribution (lenny), this problem has been fixed in version 1.5.1dfsg1-5.
