MEDIUM 4.6DOWNGRADE

CVE-2003-0337 is a medium-severity flaw (CVSS 4.6) affecting lsadmin. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The ckconfig command in lsadmin for Load Sharing Facility (LSF) 5.1 allows local users to execute arbitrary programs by modifying the LSF_ENVDIR environment variable to reference an alternate lsf.conf file, then modifying LSF_SERVERDIR to point to a malicious lim program, which lsadmin then executes.

platform lsadmin DOWNGRADE

Affected: 5.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.1 (Debian / Ubuntu)

apt-cache madison lsadmin sudo apt install lsadmin=<VERSION_BEFORE_5.1> sudo apt-mark hold lsadmin

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

dnf --showduplicates list lsadmin sudo dnf downgrade lsadmin-<VERSION_BEFORE_5.1> sudo dnf versionlock add lsadmin

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.
