| 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. 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, this problem has been fixed in version 1.5.1dfsg1-5. For the testing distribution, this problem has been fixed in version 1.6.12dfsg-2. For the unstable distribution, this problem has been fixed in version 1.6.12dfsg-2. We recommend that you upgrade your samba packages. |
