Flera sårbarheter har upptäckts i EXIF-tolkningskoden i biblioteket libexif, vilket kunde användas i en överbelastningsattack eller till exekvering av godtycklig kod om en användare lurades att öppna en felformaterad bild. Projektet Common Vulnerabilities and Exposures identifierar följande problem:

CVE-2007-6352

Denna uppdatering rättar även två potentiella NULL-pekaravrefereringar.

För den gamla stabila utgåvan (Sarge) har dessa problem rättats i 0.6.9-6sarge2.

För den stabila utgåvan (Etch) har dessa problem rättats i version 0.6.13-5etch2.

Vi rekommenderar att ni uppgraderar era libexif-paket.
