Endpoint Vulnerability

Mozilla Windows updater can be run outside of application directory


Security researcher Holger Fuhrmannek previously reported CVE-2015-0833, which was fixed in MFSA2015- 12. That flaw allowed for the updater to load binary DLL format files from the local working directory or from the Windows temporary directories. During the fixing of CVE-2015-0833, the need to ensure that updates use the updater.exe from the application directory was identified to mitigate the potential for further similar vulnerabilities. This change to updater.exe for Windows systems has been made in this release.
