RedHat: RHSA-2019-4785 Critical: ImageMagick Security Flaw Detected

An update for ghostscript is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: ghostscript security update Advisory ID: RHSA-2018:3760-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:3760 Issue date: 2018-12-03 CVE Names: CVE-2018-16509 ==================================================================== 1. Summary: An update for ghostscript is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed. Security Fix(es): * It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker couldpossibly exploit this to bypass the - -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document. (CVE-2018-16509) Red Hat would like to thank Tavis Ormandy (Google Project Zero) for reporting this issue. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5.

Red Hat Linux 7: RHSA-2001:154-06 Critical: OpenSSH Command Bypass

These updates fix a bug in handling of restricted keys which mayallow users to bypass command restrictions by using subsystems and a subtlebug which might aid a passive analysis attack.. ` --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated OpenSSH packages available Advisory ID: RHSA-2001:154-06 Issue date: 2001-11-13 Updated on: 2001-11-30 Product: Red Hat Linux Keywords: openssh restricted commands echo Cross references: Obsoletes: RHSA-2001:114 --------------------------------------------------------------------- 1. Topic: Updated OpenSSH packages are now available for Red Hat Linux 7, 7.1, and 7.2. These updates fix a bug in handling of restricted keys which may allow users to bypass command restrictions by using subsystems and a subtle bug which might aid a passive analysis attack. 2. Relevant releases/architectures: Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386 3. Problem description: OpenSSH versions prior to 2.9.9, when configured to provide sftp access using the subsystem feature, allows remote authenticated users to bypass authorized_keys2 "command=" restrictions by using sftp commands. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2001-0816 to this issue. OpenSSH 2.9 also contained a subtle bug in the routines which attempt to confound an attacker using passive analysis, which would cause it to send two confounding packets instead of one when a client finished sending it a password. Red Hat would like to thank Solar Designer and Markus Friedl for assisting with the patches. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
