Gentoo Linux Security Advisory

Title: Subversion: Metadata information leak (GLSA 200409-35)
Severity: low
Exploitable: remote
Date: September 29, 2004
Bug(s): #65085
ID: 200409-35

Synopsis


An information leak in mod_authz_svn could allow sensitive metadata of
protected areas to be leaked to unauthorized users.


Background


Subversion is a versioning system designed to be a replacement for CVS.
mod_authz_svn is an Apache module to do path-based authentication for
Subversion repositories.


Affected Packages

Package: dev-util/subversion
Vulnerable: < 1.0.8
Unaffected: >= 1.0.8
Architectures: All supported architectures


Description


There is a bug in mod_authz_svn that causes it to reveal logged metadata
regarding commits to protected areas.


Impact


Protected files themselves will not be revealed, but an attacker could use
the metadata to reveal the existence of protected areas, such as paths,
file versions, and the commit logs from those areas.


Workaround


Rather than using mod_authz_svn, move protected areas into seperate
repositories and use native Apache authentication to make these
repositories unreadable.


Resolution


All Subversion users should upgrade to the latest version:
