TITLE

zlib  Out-of-bounds write vulnerability in

DESCRIPTION

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). zlib Exists in an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ========================================================================== Ubuntu Security Notice USN-5570-2 October 17, 2022 zlib vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS Summary: zlib could be made to crash or run programs if it received specially crafted input. This update provides the corresponding update for Ubuntu 22.04 LTS and Ubuntu 20.04 LTS. Original advisory details: Evgeny Legerov discovered that zlib incorrectly handled memory when performing certain inflate operations. An attacker could use this issue to cause zlib to crash, resulting in a denial of service, or possibly execute arbitrary code. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: lib32z1 1:1.2.11.dfsg-2ubuntu9.2 lib64z1 1:1.2.11.dfsg-2ubuntu9.2 libx32z1 1:1.2.11.dfsg-2ubuntu9.2 zlib1g 1:1.2.11.dfsg-2ubuntu9.2 Ubuntu 20.04 LTS: lib32z1 1:1.2.11.dfsg-2ubuntu1.5 lib64z1 1:1.2.11.dfsg-2ubuntu1.5 libx32z1 1:1.2.11.dfsg-2ubuntu1.5 zlib1g 1:1.2.11.dfsg-2ubuntu1.5 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5218-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso August 25, 2022 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : zlib CVE ID : CVE-2022-37434 Debian Bug : 1016710 Evgeny Legerov reported a heap-based buffer overflow vulnerability in the inflate operation in zlib, which could result in denial of service or potentially the execution of arbitrary code if specially crafted input is processed. For the stable distribution (bullseye), this problem has been fixed in version 1:1.2.11.dfsg-2+deb11u2. We recommend that you upgrade your zlib packages. Summary: Updated rh-sso-7/sso76-openshift-rhel8 container image and rh-sso-7/sso7-rhel8-operator-bundle image is now available for RHEL-8 based Middleware Containers. Description: The rh-sso-7/sso76-openshift-rhel8 container image and rh-sso-7/sso7-rhel8-operator operator has been updated for RHEL-8 based Middleware Containers to address the following security issues. Users of rh-sso-7/sso76-openshift-rhel8 container images and rh-sso-7/sso7-rhel8-operator operator are advised to upgrade to these updated images, which contain backported patches to correct these security issues, fix these bugs and add these enhancements.

Summary: An update for rsync is now available for Red Hat Enterprise Linux 9. 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 (v. 9) - noarch Red Hat Enterprise Linux BaseOS (v. 9) - aarch64, ppc64le, s390x, x86_64 3. Description: The rsync utility enables the users to copy and synchronize files locally or across a network. Synchronization with rsync is fast because rsync only sends the differences in files over the network instead of sending whole files. The rsync utility is also used as a mirroring tool. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.1 Release Notes linked from 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.
