CVE-2006-0803
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe signature verification functionality in the YaST Online Update (YOU) script handling relies on a gpg feature that is not intended for signature verification, which prevents YOU from detecting malicious scripts or code that do not pass the signature check when gpg 1.4.x is being used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe YaST Online Update (YOU) script uses an incorrect GPG feature for signature verification—one not designed for that purpose—which allows malicious unsigned or improperly signed scripts to pass through when gpg 1.4.x is used, bypassing the security check entirely.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SUSE Linux versionRun 'cat /etc/SuSE-release' or 'lsb_release -a' to determine the installed SUSE versionAffected if Version is 9.3 or 10.0 (the affected versions)
-
Check GPG version in useRun 'gpg --version' and note the major.minor version numberAffected if GPG version 1.4.x is installed (the vulnerable GPG version)
-
Locate the YOU scriptFind the yaST Online Update script, typically at /usr/bin/you or /sbin/yast2 online_update, or search with 'find /usr -name "*online_update*" -type f'Affected if The YOU script exists on the system (prerequisite for the vulnerability)
-
Examine YOU script GPG verification methodOpen the YOU script in a text editor or use 'grep -i gpg' on the script file to find signature verification commandsAffected if The script uses '--armor' or '--detach-sign' or other GPG options not designed for verification of downloaded files (the incorrect GPG feature)
-
Verify unsigned or improperly signed update packages can executeAttempt to run an unsigned update through YOU or examine the script's handling of missing/invalid GPG signaturesAffected if The script proceeds without properly validating GPG signatures (allows bypass)
A system is affected if it is SUSE Linux 9.3 or 10.0, uses GPG 1.4.x, and the YOU script employs an incorrect GPG verification method that fails to properly validate signatures.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataModify the YOU script to use the proper GPG signature verification feature intended for that use case, or ensure compatibility with GPG versions that correctly handle signature validation.
