Gentoo Linux Security Advisory GLSA 200409-35
Severity: Low SynopsisAn information leak in mod_authz_svn could allow sensitive metadata of protected areas to be leaked to unauthorized users. BackgroundSubversion 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
DescriptionThere is a bug in mod_authz_svn that causes it to reveal logged metadata regarding commits to protected areas. ImpactProtected 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. WorkaroundRather than using mod_authz_svn, move protected areas into seperate repositories and use native Apache authentication to make these repositories unreadable. ResolutionAll Subversion users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=dev-util/subversion-1.0.8"
# emerge ">=dev-util/subversion-1.0.8"
