(Subversion: Vulnerability in mod_authz_svn)
Users with write access to part of a Subversion repository may bypass read

This is a low-risk vulnerability. It affects only users of Subversion who
are running servers inside Apache and using mod_authz_svn. Additionally,
this vulnerability may be exploited only by users with write access to some
portion of a repository.
Keep sensitive content separated into different Subversion repositories, or
disable the Apache Subversion server and use svnserve instead.
All Subversion users should upgrade to the latest available version:
# emerge sync
# emerge -pv ">=dev-util/subversion-1.0.6"
# emerve ">=dev-util/subversion-1.0.6"
