AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Under certain conditions, phpMyAdmin fails to delete temporary files during ESRI file imports, enabling a denial-of-service attack via disk exhaustion.
Vulnerability
An issue exists in phpMyAdmin where temporary files created during the import of ESRI (shapefile) data are not reliably deleted. This affects all 4.6.x versions prior to 4.6.4, all 4.4.x versions prior to 4.4.15.8, and all 4.0.x versions prior to 4.0.10.17 [1][3]. The vulnerability only manifests when PHP is running with the dbase extension, which is not shipped by default and is rarely available [3].
Exploitation
An attacker must have the ability to import ESRI files into phpMyAdmin (typically requiring authenticated access) and the target PHP environment must have the dbase extension enabled. By uploading a crafted ESRI file, the import process leaves behind temporary files that are not cleaned up. Repeated imports can cause these files to accumulate [1][3].
Impact
Successful exploitation leads to disk space exhaustion on the server, resulting in a denial-of-service (DoS) condition. The vulnerability is classified as non-critical by phpMyAdmin, but it can disrupt normal operations by filling the filesystem [3][4]. No disclosure of sensitive data, modification of files, or remote code execution is involved [1].
Mitigation
Users should upgrade to phpMyAdmin 4.6.4, 4.4.15.8, or 4.0.10.17 (or later) as released on 2016-07-25 [3]. Patches are available in the respective Git branches (commits 6f8eb09, e31ac0b, 48764f2) [3]. If upgrading is not immediately possible, disabling or removing the dbase PHP extension entirely eliminates the vulnerable code path [3]. No other workarounds are documented.
