CVE-2004-0749 is a medium-severity flaw (CVSS 5.0) affecting subversion, linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The mod_authz_svn module in Subversion 1.0.7 and earlier does not properly restrict access to all metadata on unreadable paths, which could allow remote attackers to gain sensitive information via (1) svn log -v, (2) svn propget, or (3) svn blame, and other commands that follow renames.

subversion subversion DOWNGRADE

Affected: 1.0 · 1.0.1 · 1.0.2 · 1.0.3 · 1.0.4 · 1.0.5 · 1.0.6 · 1.0.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0

1. Check installed version

apt-cache policy subversion || rpm -q subversion || subversion --version

2. No fixed release: DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison subversion sudo apt install subversion=<VERSION_BEFORE_1.0> sudo apt-mark hold subversion

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list subversion sudo dnf downgrade subversion-<VERSION_BEFORE_1.0> sudo dnf versionlock add subversion

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
