Summary: An update for binutils is now available for Red Hat Enterprise Linux 8.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 AppStream EUS (v. 8.2) - aarch64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS EUS (v. 8.2) - aarch64, ppc64le, s390x, x86_64 3. Description: The binutils packages provide a collection of binary utilities for the manipulation of object code in various object file formats. It includes the ar, as, gprof, ld, nm, objcopy, objdump, ranlib, readelf, size, strings, strip, and addr2line utilities. Security Fix(es): * Developer environment: Unicode's bidirectional (BiDi) override characterscan cause trojan source attacks (CVE-2021-42574) The following changes were introduced in binutils in order to facilitate detection of BiDi Unicode characters: Tools which display names or strings (readelf, strings, nm, objdump) have a new command line option --unicode / -U which controls how Unicode characters are handled. Using"--unicode=default" will treat them as normal for the tool. This is the default behaviour when --unicode option is not used. Using "--unicode=locale" will display them according to the current locale. Using "--unicode=hex" will display them as hex byte values. Using "--unicode=escape" will display them as Unicode escape sequences. Using "--unicode=highlight" will display them as Unicode escape sequences highlighted in red, if supported by the output device. For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. 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.

security advisoryRed Hat LinuxmoderateRed Hat Linux 7.1 RHSA-2003:199-02 Moderate: Unzip File Overwrite
Updated unzip packages resolving a vulnerability allowing arbitrary filesto be overwritten are now available.. ` --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated unzip packages fix trojan vulnerability Advisory ID: RHSA-2003:199-02 Issue date: 2003-07-01 Updated on: 2003-08-15 Product: Red Hat Linux Keywords: unzip control charactersCross references: Obsoletes: RHSA-2002:096 CVE Names: CAN-2003-0282 --------------------------------------------------------------------- 1. Topic: Updated unzip packages resolving a vulnerability allowing arbitrary files to be overwritten are now available. [Updated 15 August 2003] Ben Laurie found that the original patch to fix this issue missed a case where the path component included a quoted slash. These updated packages contain a new patch that corrects this issue. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.1 for iSeries (64 bit) - ppc Red Hat Linux 7.1 for pSeries (64 bit) - ppc Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: The unzip utility is used for manipulating archives, which are multiple files stored inside of a single file. A vulnerabilitiy in unzip version 5.50 and earlier allows attackers to overwrite arbitrary files during archive extraction by placing invalid (non-printable) characters between two "." characters. These non-printable characters are filtered, resulting in a ".." sequence. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0282 to this issue. This erratum includes a patch ensuring that non-printable characters do not make it possible for a malicious .zip file to write to parent directories unless the "-:" command line parameter is specified. Users of unzip are advised to upgrade to these updated packages, which are not vulnerableto this issue. 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. Bug IDs fixed ( for more info): 97301 - vulnerability in unzip 5.50 allows malicious zip file to write to ../ 6. RPMs required: Red Hat Linux 7.1: SRPMS: i386: Red Hat Linux 7.1 for iSeries (64 bit): SRPMS: ppc: Red Hat Linux 7.1 for pSeries (64 bit): SRPMS: ppc: Red Hat Linux 7.2: SRPMS: i386: ia64: Red Hat Linux 7.3: SRPMS: i386: Red Hat Linux 8.0: SRPMS: i386: Red Hat Linux 9: SRPMS: i386: 7.
