TITLE

macOS High Sierra Access vulnerability

DESCRIPTION

In macOS High Sierra before 10.13.5, an issue existed in CUPS. This issue was addressed with improved access restrictions. Apple macOS High Sierra is a set of dedicated operating systems developed by Apple (Apple) for Mac computers. CUPS is one of the open source printing system components for OS X and Unix-like systems. ========================================================================== Ubuntu Security Notice USN-3713-1 July 11, 2018 cups vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 17.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in CUPS. A remote attacker could possibly use this issue to cause CUPS to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 17.10 and Ubuntu 18.04 LTS. (CVE-2017-18248) Dan Bastone discovered that the CUPS dnssd backend incorrectly handled certain environment variables. A local attacker could possibly use this issue to escalate privileges. (CVE-2018-4180) Eric Rafaloff and John Dunlap discovered that CUPS incorrectly handled certain include directives. A local attacker could possibly use this issue to read arbitrary files. (CVE-2018-4181) Dan Bastone discovered that the CUPS AppArmor profile incorrectly confined the dnssd backend. A local attacker could possibly use this issue to escape confinement. (CVE-2018-6553) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: cups 2.2.7-1ubuntu2.1 Ubuntu 17.10: cups 2.2.4-7ubuntu3.1 Ubuntu 16.04 LTS: cups 2.1.3-4ubuntu0.5 Ubuntu 14.04 LTS: cups 1.7.2-0ubuntu1.10 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: cups security and bug fix update Advisory ID: RHSA-2020:1050-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:1050 Issue date: 2020-03-31 CVE Names: CVE-2018-4180 CVE-2018-4181 CVE-2018-4700 ==================================================================== 1.

These issues have been identified with the following CVE ids: CVE-2017-15400 Rory McNamara discovered that an attacker is able to execute arbitrary commands (with the privilege of the CUPS daemon) by setting a malicious IPP server with a crafted PPD file. CVE-2018-4182 Dan Bastone of Gotham Digital Science discovered that an attacker with sandboxed root access can execute backends without a sandbox profile by provoking an error in CUPS' profile creation. CVE-2018-4183 Dan Bastone and Eric Rafaloff of Gotham Digital Science discovered that an attacker with sandboxed root access can execute arbitrary commands as unsandboxed root by modifying /etc/cups/cups-files.conf CVE-2018-6553 Dan Bastone of Gotham Digital Science discovered that an attacker can bypass the AppArmor cupsd sandbox by invoking the dnssd backend using an alternate name that has been hard linked to dnssd. For the stable distribution (stretch), these problems have been fixed in version 2.2.1-8+deb9u2. We recommend that you upgrade your cups packages.
