Regardless of how you plan on applying these critical OS X updates, UpGuard's OVAL-backed vulnerability scanner can automatically identify which nodes are at-risk on an ongoing basis.Mac users are being urged to update to macOS Big Sur 11.3 as at least one threat group is exploiting the zero-day bug to sneak past the operating system’s built-in security mechanismsĪpple has rolled out an update for its macOS Big Sur operating system to address a bevy of security flaws, including a vulnerability that could allow malware to circumvent the operating system’s built-in protection mechanisms. However, in some cases it may not be possible (or feasible) to perform such updates en masse-these scenarios may require patches to be downloaded and applied in a specific manner. Upgrading your OS X-based nodes to the latest version can effectively remediate these vulnerabilities. New error logging features in OS X 10.10 that include unsafe additions to the dynamic linker could allow local attackers to gain unfettered root privileges. The kernel in OS X before 10.10.5 does not properly mount HFS volumes, which could allow local users to cause a denial-of-service (DoS) via a crafted volume. Mail in OS X before 10.9 (with Kerberos authentication enabled and TLS disabled) sends invalid cleartext data, which could allow remote attackers to obtain sensitive information by simply sniffing network traffic. Mail/Kerberos Authentication Vulnerability This allows local users to obtain sensitive data by reading storage media (e.g., flash drive). The Secure Empty Trash feature in Finder in OS X before 10.11 improperly deletes Trash files.

This could allow a man-in-the-middle attacker to execute arbitrary code by spoofing the HTTP server. The User Documentation component in OS X through 10.6.8 uses HTTP sessions for updates to App Store help information.

The UserAccountUpdater in OS X 10.10 before 10.10.2 stores a PDF document's password in a printing preference file, allowing local users to obtain sensitive information by reading said file 7. The App Store process in CommerceKit Framework in OS X before 10.10.2 places Apple ID credentials in App Store logs, which could allow local users to obtain sensitive information by simply reading the log files. LaunchServices in OS X before 10.10.3 could allow local attackers to cause a denial-of-service (Finder crash) via specially crafted localization data. Updating to version 10.11 or higher effectively remediates this vulnerability.

This could allow physically proximate attackers to bypass the screen-lock protection mechanism and enter characters into an arbitrary window under the lock window via keyboard input.

The Security-Keychain component in versions of OS X before 10.9.4 does not properly implement keystroke observers. This could allow remote attackers to obtain sensitive information by reading a message intended exclusively for other recipients. Versions of Mail before 10.10 do not properly recognize the removal of a recipient address from a message. Newer versions of OS X do not have this flaw, so upgrading to a newer version effectively remediates the vulnerability. This could allow attackers in physical proximity to access an unattended workstation. The Dock in Apple OS X versions before 10.10 improperly manages the screen-lock state. The following are the top 11 OS X vulnerabilities and exploitation prevention tips. OS X may be considered Apple's desktop OS magnum opus, but it certainly hasn't been without its share of vulnerabilities ( 1,250 to date per the CVE database).
