Published: Translated: NVD NIST

Summary

An insecure temporary file vulnerability in openSUSE sdbootutil allows local users to pre-create a directory to access private information in /var/lib/pcrlock.d, manipulate backup data in /tmp/pcrlock.d.bak, or overwrite protected system files via symlinks.

Risk Assessment

The risk includes confidentiality breach (access to private data) and integrity violation (backup manipulation and system file overwrite), potentially leading to privilege escalation or system compromise.

Recommendation

Immediately update sdbootutil to a patched version (commit 5880246d3a02642dc68f5c8cb474bf63cdb56bca) and restrict local access where possible.

Original NVD description (English source)

An Insecure Temporary File vulnerability in openSUSE sdbootutil allows local users to pre-create a directory to achieve various effects like: * gain access to possible private information found in /var/lib/pcrlock.d * manipulate the data backed up in /tmp/pcrlock.d.bak, therefore violating the integrity of the data should it be restored. *  overwrite protected system files with data from /var/lib/pcrlock.d by placing symlinks to existing files in the directory tree in /tmp/pcrlock.d.bak. This issue affects sdbootutil: from ? before 5880246d3a02642dc68f5c8cb474bf63cdb56bca.
