CVE-2007-0472: Multiple race conditions in Smb4K before 0.8.0 allow local users to (1) modify arbitrary files via unspecified

Routine

LOW 3.7DOWNGRADE

CVE-2007-0472 is a low-severity flaw (CVSS 3.7) affecting smb4k. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Multiple race conditions in Smb4K before 0.8.0 allow local users to (1) modify arbitrary files via unspecified manipulations of Smb4K's lock file, which is not properly handled by the remove_lock_file function in core/smb4kfileio.cpp, and (2) add lines to the sudoers file via a symlink attack on temporary files, which isn't properly handled by the writeFile function in core/smb4kfileio.cpp.

Why this priority

No elevated risk signals yet

No fix is published yet: follow the downgrade or mitigation steps.

smb4k smb4k DOWNGRADE

Affected: 0.4 · 0.5 · 0.6 · 0.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.4

1. Check installed version

apt-cache policy smb4k || rpm -q smb4k || smb4k --version

2. No fixed release: DOWNGRADE to a release before 0.4 (Debian / Ubuntu)

apt-cache madison smb4k sudo apt install smb4k=<VERSION_BEFORE_0.4> sudo apt-mark hold smb4k

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

dnf --showduplicates list smb4k sudo dnf downgrade smb4k-<VERSION_BEFORE_0.4> sudo dnf versionlock add smb4k

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.
