If you’re using Arq on a Mac, please download and run the 5.10 installer<\/strong> to get an update that fixes<\/a> a security vulnerability (see details below).<\/p>\n

    \n
  1. Click this link to download the installer DMG: Arq 5.10<\/a><\/li>\n

    Arq for Mac Vulnerabilities Fixed<\/h3>\n

    Mark Wadham<\/a> (thank you Mark for all your help identifying and helping to resolve this!) identified a vulnerability in Arq 5 for Mac where an attacker could become “root” user. The issue was the way Arq applied the set-user-ID-on-execution bit to helper apps (for auto-updating, backup using administrator privileges, and restoring). The affected helper apps were arq_updater (for auto-update), arqcommitter (for backing up) and standardrestorer, arqglacierrestorer and arqs3glacierrestorer (for restoring). The fix for this issue is implemented in Arq 5.10:<\/p>\n

      \n
    1. When you double-click the Arq icon in the DMG, Arq copies itself to \/Applications and sets the permissions on the application bundle to prevent non-root users from modifying it.<\/li>\n
    2. Arq will only set the set-user-ID-on-execution bit on the helper apps if the Arq app bundle is installed in \/Applications.<\/li>\n<\/ol>\n

      Arq 5.10.0 for Windows<\/h3>\n

      If you’re using Arq 5 on Windows, we just shipped an update that contains numerous bug fixes<\/a>. Please pick “Check for Updates” from Arq’s menu to get the 5.10.0 update. Or, run the 5.10.0 installer<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
